In recent years, much interest was devoted to the Urysohn space and its isometry group. We also study Green algebra A(kG) generated by the isomorphism classes of indecomposable kG-modules. We then offer an elementary proof of pontryagin duality theorem for compact and discrete abelian groups. we extend the locally quasi-convex abelian group to maximally almost-periodic non-necessarily abelian groups. In this work, we are interested in constructing a C^{1} action on the interval of a special and universal nilpotent group denoted by N.

This paper is an improvement of our paper “(t, i, f)-Neutrosophic Structures” [1], where we introduced for the first time a new type of structures, called (t, i, f)-Neutrosophic Structures, presented from a neutrosophic logic perspective, and we showed particular cases of such structures in geometry and in algebra.
In any field of knowledge, each structure is com-posed from two parts: a space, and a set of axioms (or laws) acting (governing) on it. If the space, or at least one of its axioms (laws), has some indeterminacy of the form (t, i, f) ≠ (1, 0, 0), that structure is a (t, i, f)-Neutrosophic Structure.
The (t, i, f)-Neutrosophic Structures [based on the components t = truth, i = numerical indeterminacy, f = falsehood] are different from the Neutrosophic Algebraic Structures [based on neutrosophic numbers of the form a + bI, where I = literal indeterminacy and In = I], that we rename as I-Neutrosophic Algebraic Structures (meaning algebraic structures based on indeterminacy “I” only). But we can combine both and obtain the (t, i, f)-I-Neutrosophic Algebraic Structures, i.e. algebraic struc-tures based on neutrosophic numbers of the form a+bI, but also having indeterminacy of the form (t, i, f) ≠ (1, 0, 0) related to the structure space (elements which only partially belong to the space, or elements we know noth-ing if they belong to the space or not) or indeterminacy of the form (t, i, f) ≠ (1, 0, 0) related to at least one axiom (or law) acting on the structure space. Then we extend them to Refined (t, i, f)- Refined I-Neutrosophic Algebra-ic Structures.

In this paper we solve a previously formulated conjecture. That is, for the cocommutative irreducible coalgebra C. we also introduce the azumaya coalgebras over a cocommutative coalgebra R. the computation of the brauer group BM of modified supergroup algebras over a field is performed, yielding the computation of the brauer group of all finite-dimensional triangular hopf algebra. Then we address the question if the cartan matrix of a block of a finite group cannot be arranged as a direct sum of smallest matrices. The aim of our work is to show that the topological hochschild homology of a discrete ring and the maclane homology of R are isomorphic.

Each finite group is a subgroup of some symmetric group, known as the Cayley theorem.
We find the symmetric group of smallest order which hosts the finite groups
in that sense for
most groups of order less than 37.
For each of these small groups this is made concrete by providing a permutation group
with a minimum number of moved elements in terms of a list of generators
of the permutation group in reduced cycle notation.

This study is different from that of the algebraic structures using the interval [0, n) n ≠ 1, as these structures on [0, 1) has no idempotents or zero divisors under ×. Further [0, 1) under product × is only a semigroup. However by defining min(or max) operation in [0, 1); [0, 1) is made into a semigroup.

Prime numbers have always fascinated mankind. For mathematicians, they are a kind of “black sheep” of the family of integers by their constant refusal to let themselves to be disciplined, ordered and understood. However, we have at hand a powerful tool, insufficiently investigated yet, which can help us in understanding them: Fermat pseudoprimes. It was a night of Easter, many years ago, when I rediscovered Fermat’s "little" theorem. Excited, I found the first few Fermat absolute pseudoprimes (561, 1105, 1729, 2465, 2821, 6601, 8911…) before I found out that these numbers are already known. Since then, the passion for study these numbers constantly accompanied me.

In this book, we define several new neutrosophic algebraic structures and their related properties. The main focus of this book is to study the important class of neutrosophic rings such as neutrosophic LA-semigroup ring, neutrosophic loop ring, neutrosophic groupoid ring and so on. We also construct their generalization in each case to study these neutrosophic algebraic structures in a broader sense. The indeterminacy element “I“ gives rise to a bigger algebraic structure than the classical algebraic structures. It mainly classifies the algebraic structures in three categories such as: neutrosophic algebraic structures, strong neutrosophic algebraic structures, and classical algebraic structures respectively. This reveals the fact that a classic algebraic structure is a part of the neutrosophic algebraic structures. This opens a new way for the researcher to think in a broader way to visualize these vast neutrosophic algebraic structures.

In this book, the authors define several new types of soft neutrosophic algebraic structures over neutrosophic algebraic structures and we study their generalizations. These soft neutrosophic algebraic structures are basically parameterized collections of neutrosophic sub-algebraic structures of the neutrosophic algebraic structure. An important feature of this book is that the authors introduce the soft neutrosophic group ring, soft neutrosophic semigroup ring with its generalization, and soft mixed neutrosophic N-algebraic structure over neutrosophic group ring, then the neutrosophic semigroup ring and mixed neutrosophic N-algebraic structure respectively.

In this paper we prove the generalized continuum hypothesis by categorical logic which is as the theory of categories a first-order theory and so is a logically complete theory.
To prove that the theory of initial ordinals and the theory of transfinite cardinals are isomorphic, that is, to prove that the theorems of the theory of transfinite cardinals are also theorems of the theory of initial ordinals and conversely, the theorems of the theory of initial ordinals are also theorems of the theory of transfinite cardinals, since the theories of isomorphic structures are isomorphic theories by the fundamental theorem of mathematical logic and the theories of isomorphic categories are isomorphic theories which is the fundamental theorem of categorical logic for isomorphic categories are isomorphic structures, we prove these structures are isomorphic categories.
We use the definition of a theory, the definition of an isomorphism of structures in its equivalent form the definition of an isomorphism of categories, the definition of a functor, the axioms of the theory of categories and the axioms of mathematical logic, so as to apply both the theorem on the comparablity of initial ordinals to the theory of transfinite cardinals and the fundamental theorem of transfinite cardinal arithmetic to the theory of initial ordinals.

Study of soft sets was first proposed by Molodtsov in 1999 to deal with uncertainty in a non-parametric manner. The researchers did not pay attention to soft set theory at that time but now the soft set theory has been developed in many areas of mathematics.
Algebraic structures using soft set theory are very rapidly developed. In this book we developed soft neutrosophic algebraic structures by using soft sets and neutrosophic algebraic structures. In this book we study soft neutrosophic groups, soft neutrosophic semigroups, soft neutrosophic loops, soft neutrosophic LA-semigroups, and their generalizations respectively.

There are three types of Smarandache Algebraic Structures:
1.A Smarandache Strong Structure on a set S means a structure on S that has a proper subset P with a stronger structure.
2.A Smarandache Weak Structure on a set S means a structure on S that has a proper subset P with a weaker structure.
3.A Smarandache Strong-Weak Structure on a set S means a structure on S that has two proper subsets: P with a stronger structure, and Q with a weaker structure.
By proper subset of a set S, one understands a subset P of S, different from the empty set, from the original set S, and from the idempotent elements if any.
Having two structures {u} and {v} defined by the same operations, one says that structure {u} is stronger than structure {v}, i.e. {u} > {v}, if the operations of {u} satisfy more axioms than the operations of {v}.
Each one of the first two structure types is then generalized from a 2-level (the sets P ⊂ S and their corresponding strong structure {w1}>{w0}, respectively their weak structure {w1}<{w0}) to an n-level (the sets Pn-1 ⊂ Pn-2 ⊂ … ⊂ P2 ⊂ P1 ⊂ S and their corresponding strong structure {wn-1} > {wn-2} > … > {w2} > {w1} > {w0}, or respectively their weak structure {wn-1} < {wn-2} < … < {w2} < {w1} < {w0}). Similarly for the third structure type, whose generalization is a combination of the previous two structures at the n-level.
A Smarandache Weak BE-Algebra X is a BE-algebra in which there exists a proper subset Q such that 1 belongs to Q, |Q| ≥ 2, and Q is a CI-algebra.
And a Smarandache Strong CI-Algebra X is a CI-algebra X in which there exists a proper subset Q such that 1 belongs to Q, |Q| ≥ 2, and Q is a BE-algebra.
The book elaborates a recollection of the BE/CI-algebras, then introduces these last two particular structures and studies their properties.

The authors have constructed subset semirings using rings of both finite and infinite order. Thus, using finite rings we construct infinite number of finite semirings, both commutative as well as non-commutative, which is the main advantage of using this algebraic structure. For finite distribute lattices alone contribute for finite semirings.

Exactly 125 years ago G. Peano introduced the modern concept of vectors
in his 1888 book "Geometric Calculus - According to the Ausdehnungslehre (Theory of
Extension) of H. Grassmann". Unknown to Peano, the young British mathematician
W. K. Clifford (1846-1879) in his 1878 work "Applications of Grassmann's Extensive
Algebra" had already 10 years earlier perfected Grassmann's algebra to the modern
concept of geometric algebras, including the measurement of lengths (areas and volumes)
and angles (between arbitrary subspaces). This leads currently to new ideal methods for
vector field computations in geometric algebra, of which several recent exemplary results
will be introduced.

The authors in this book construct a large class of finite subset groupoids as well as a large class of infinite subset groupoids. Here the conditions under which these subset groupoids satisfy special identities like Bol Identity, Moufang Identity, right alternative identity and so on are found.
In fact, it is an open problem to find subset groupoids to satisfy special identities, even if the groupoid over which they are defined do not satisfy the special identities.

In math, especially within the Lie Algebra groups, there exist a small group of "exceptional isomorphisms" or "accidental isomorphisms." Following the lead of Swiss psychologist Carl Jung, the author does not accept the existence of "exceptional" or "accidental;" instead, these are merely phenomena which heretofore have not been explained satisfactorily by mathematical theory. However, articulation of the Qi Men Dun Jia Cosmic Board Model in a recent and forthcoming paper has helped to explain several of the exceptional isomorphisms.

The aim of this work is to show how the geometric product of multivectors is defined in
general, extending the basic geometric product of vectors given by Clifford. An alternative
definition of Clifford geometric algebra, that guarantees existence as quotient algebra of
the tensor algebra was given by Chevalley in 1954.[2] We further treat the scalar product, the outer product, the cross product in three dimensions, linear dependence and independence, as well as right- and left contractions.

This paper focuses on the symmetries of crystal space lattices. All two dimensional
(2D) and three dimensional (3D) point groups of 2D and 3D crystal cells are exclusively described
by vectors (two in 2D, three in 3D for one particular cell) taken from the physical cells. Geometric
multiplication of these vectors completely generates all symmetries, including reflections,
rotations, inversions, rotary-reflections and rotary-inversions. We then extend this treatment to 3D
space groups by including translations, glide reflections and screw rotations. We focus on the
monoclinic case as an example. A software demonstration shows the spacegroup visualizer.

Conventional illustrations of the rich elementary relations and physical applications of geometric algebra are helpful,
but restricted in communicating full generality and time dependence. The main restrictions are one special perspective
in each graph and the static character of such illustrations. Several attempts have been made to overcome such
restrictions. But up till now very little animated and fully interactive, free, instant access, online material is available.
This report presents therefore a set of over 90 newly developed (freely online accessible [1]) JAVA
applets. These applets range from the elementary concepts of vector, bivector, outer product and rotations to triangle
relationships, oscillations and polarized waves. A special group of 21 applets illustrates three geometrically different
approaches to the representation of conics; and even more ways to describe ellipses. Next Clifford's famous circle chain
theorem is illustrated. Finally geometric applications important for crystallography and structural mechanics give a
glimpse of the vast potential for applied mathematics. The interactive geometry software Cinderella [2]
was used for creating these applets. The interactive features of many of the applets invite the user to freely explore
by a few mouse clicks as many different special cases and perspectives as he likes. This is of great help in "visualizing"
geometry encoded by geometric algebra.

This paper first reviews how anti-symmetric matrices in two dimensions yield
imaginary eigenvalues and complex eigenvectors. It is shown how this carries on to
rotations by means of the Cayley transformation. Then the necessary tools from real
geometric algebra are introduced and a real geometric interpretation is given to the
eigenvalues and eigenvectors. The latter are seen to be two component eigenspinors
which can be further reduced to underlying vector duplets. The eigenvalues are
interpreted as rotors, which rotate the underlying vector duplets. The second part of
this paper extends and generalizes the treatment to three dimensions. The final part
shows how all entities and relations can be obtained in a constructive way, purely
assuming the geometric algebras of 2-space and 3-space.

This paper briefly reviews the conventional method of obtaining the canonical form of an antisymmetric (skew-symmetric, alternating) matrix. Conventionally a vector space over the complex field has to be introduced. After a short introduction to the universal mathematical "language" Geometric Calculus, its fundamentals, i.e. its "grammar" Geometric Algebra (Clifford Algebra) is explained. This lays the groundwork for its real geometric and coordinate free application in order to obtain the canonical form of an antisymmetric matrix in terms of a bivector, which is isomorphic to the conventional canonical form. Then concrete applications to two, three and four dimensional antisymmetric square matrices follow. Because of the physical importance of the Minkowski metric, the canonical form of an antisymmetric matrix with respect to the Minkowski metric is derived as well. A final application to electromagnetic fields concludes the work.

In [4] we have introduced Smarandache quasigroups which are Smarandache
non-associative structures. A quasigroup is a groupoid whose composition table is a Latin
square. There are squares in the Latin squares which seem to be of importance to study the
structure of Latin Squares. We consider the particular type of squares properly contained in
the Latin squares which themselves contain a Latin square. Such Latin squares are termed
as Smarandache Mukti-Squares or SMS. Extension of some SMS to Latin squares is also
considered.

The history of matrices goes back to ancient times! But the term "matrix" was not applied to the concept until 1850."Matrix" is the Latin word for womb, and it retains that sense in English. It can also mean more generally any place in which something is formed or produced. The orgins of mathematical matrices lie with the study of systems of simultaneous linear equations. An important Chinese text from between 300 BC and AD 200, Nine Chapters of the Mathematical Art (Chiu Chang Suan Shu), gives the first known example of the use of matrix methods to solve simultaneous equations. Since their first appearance in ancient China, matrices have remained important mathematical tools. Today, they are used not simply for solving systems of simultaneous linear equations, but also for describing the quantum mechanics of atomic structure, designing computer game graphics, analyzing relationships, and even plotting complicated dance steps! The elevation of the matrix from mere tool to important mathematical theory owes a lot to the work of female mathematician Olga Taussky Todd (1906-1995), who began by using matrices to analyze vibrations on airplanes during World War II and became the torchbearer for matrix theory. In this work, by applying the fundamental concepts of matrices, the author attempts to study the fifth Euclidean postulate problem and Godel’s incompleteness theorems.

Study of algebraic structures using subsets was started by George Boole. After the invention of Boolean algebra, subsets were not used in any algebraic structures.
In this book we develop algebraic structures using subsets of a set, or of a group, or semigroup, or a ring and we get algebraic structures.
Using ring or semiring we get only subset semirings.
BY the method we get an infinite number of non-commutative semirings of finite order. We build subset semivector spaces, and describe and develop interesting properties over them.

Use of fuzzy neutrosophic models in the study of social problem or technical problem has become a demand for the day due to the involvement of indeterminacy. For always one is not in the position to say true or false, or assign a fuzzy value to any problem. At times, on is not in the position to commit to any of the three statements. In that situation, neutrosophic lmodels play a vital role.
In this book we introduce several fuzzy neutrosophic models to study social problems.

In this book, the authors introduce the notion of quasi set topological vector subspaces. The
advantage of such study is that given a vector subspace we can have only one topological
space associated with the collection of all subspaces. However, we can have several
quasi set topological vector subspaces of a given vector space. Further, we have defined
topological spaces for set vector spaces, semigroup vector spaces and group vector spaces.

We convert, within polynomial-time and sequential processing, an NP-Complete Problem into a real-variable problem of minimizing a sum of Rational Linear Functions constrained by an Asymptotic-Linear-Program. The coefficients and constants in the real-variable problem are 0, 1, -1, K, or -K, where K is the time parameter that tends to positive infinity. The number of variables, constraints, and rational linear functions in the objective, of the real-variable problem is bounded by a polynomial function of the size of the NP-Complete Problem. The NP-Complete Problem has a feasible solution, if-and-only-if, the real-variable problem has a feasible optimal objective equal to zero. We thus show the strong NP-hardness of this real-variable optimization problem.

The authors introduce the concept of neutrosophic super matrices and the new notion of quasi super matrices. This new notion of quasi super matrices contains the class of super matrices. The larger class contains more partitions of the usual simple matrices. Studies in this direction are interesting and find more applications in fuzzy models. The authors also suggest in this book some open problems.

In this book the authors use set ideal of rings (or semigroups) to build topological spaces. These spaces are dependent on the set over which the set ideals are defined.
It is left as an open problem whether this newly constructed topological space of finite order increases the existing number of finite topological spaces.

Quarks are described mathematically by (3 x 3) matrices. To include these quarkonian mathematical structures into Geometric algebra it is helpful to restate Geometric algebra in the mathematical language of (3 x 3) matrices. It will be shown in this paper how (3 x 3) permutation matrices can be interpreted as unit vectors. And as S3 permutation symmetry is flavour symmetry a unified flavour picture of Geometric algebra will emerge.

A new notion of special quasi dual numbers is introduced.
If a+bg is the special quasi dual number with a, b reals, g the new element is such that g^2 = - g.
The rich source of getting new elements of the form g^2 = - g is from Z_n, the ring of modulo integers.
For the first time we construct non associative structures using them.
We have proposed some research problems.

In this book we define x = a+bg to be a special dual like number, where a, b are reals and g is a new element such that g^2 = g.
The new element which is idempotent can be got from Z_n or from lattices or from linear operators.
Mixed dual numbers are constructed using dual numbers and special dual like numbers.
Neutrosophic numbers are a natural source of special dual like numbers, since they have the form a+bI, where I = indeterminate and I^2 = I.

We introduce the new notion of tree covering a pseudo lattice. When n is an even integer of the form 2p, p a prime, then the modulo integer zero divisor graph is a tree-covering pseudo lattice.

The concept of dual numbers was introduced in 1873 by W.K.Clifford. In this book the authors build higher dimensional dual numbers, interval dual numbers and impose some algebraic structures on them. The S-vector space of dual numbers built over a Smarandache dual ring can have eigen values and eigen vectors to be dual numbers.
Complex modulo integer dual numbers and neutrosophic dual numbers are also introduced. The notion of fuzzy dual numbers can play a vital role in fuzzy models. Some research level problems are also proposed here.

that a nonempty subset F of a BE-algebra X is a Q-Smarandache filter

In this book we explore the possibility of extending the natural operations on reals to intervals and matrices. The extension to intervals makes us define a natural class of intervals in which we accept [a, b], a > b. Further, we introduce a complex modulo integer in Zn (n, a positive integer) and denote it by i_F with i_F^2 = n-1.

In this book the authors introduce a new type of product on matrices called the natural product Xn. This is an extension of product carried out in the case or row matrices of the same order.
Further, when two column matrices of same order can be added, nothing prevents one from multiplying them.
This sort of multiplication which is natural is defined as natural product Xn on matrices.

In this book the authors introduce and study the properties of natural class of intervals built using
(-∞, ∞) and (∞, -∞). The operations on these matrices with entries from natural class of intervals behave like usual reals. So working with these interval matrices takes the same time as usual matrices. Hence, when applying them to fuzzy finite element methods or finite element methods the determination of solution is simple and time saving.

This paper redefines the addition of rational numbers, in a way that allows division
by zero. This requires defining a "compensator" on the integers, plus extending
least-common-multiple (LCM) to zero and negative numbers. "Compensated addition"
defines ordinary addition on all ratios, including the 'infinities' n/0, and also
'zeroids' 0/n. The infinities and the zeroids form two 'double ringlets'. The lattice
rationals modulo the zeroids yields the infinities plus the 'wheel numbers'. Due to
the presence of the 'alternator' @ = 0/-1, double-distribution does not apply, but
triple-distribution still does.

In this paper we establish the existance of S-idempotents in case of loop rings
Z_{t}L_{n}(m) for a special class of loops L_{n}(m); over the ring of modulo integers
Z_{t} for a specific value of t. These loops satisfy the conditions g_{i}^{2} = 1 for every
g_{i} ε L_{n}(m). We prove Z_{t}L_{n}(m) has an S-idempotent when t is a perfect number
or when t is of the form 2^{i}p or 3^{i}p (where p is an odd prime) or in general when
t = p_{1}^{i}p_{2} (p_{1} and p_{2} are distinct odd primes). It is important to note that we
are able to prove only the existance of a single S-idempotent; however we leave
it as an open problem wheather such loop rings have more than one S-idempotent.
This paper has three sections. In section one, we give the basic notions about
the loops L_{n}(m) and recall the definition of S-idempotents in rings. In section
two, we establish the existance of S-idempotents in the loop ring Z_{t}L_{n}(m). In
the final section, we suggest some interesting problems based on our study.

of set linear algebras as a paradigm shift from linear algebras.
Here, the authors have also given the fuzzy parallels of these
new classes of set linear algebras.
This book abounds with examples to enable the reader to
understand these new concepts easily. Laborious theorems and
proofs are avoided to make this book approachable for nonmathematicians.
The concepts introduced in this book can be easily put to
use by coding theorists, cryptologists, computer scientists, and
socio-scientists.
Another special feature of this book is the final chapter
containing 304 problems. The authors have suggested so many
problems to make the students and researchers obtain a better
grasp of the subject.
This book is divided into seven chapters. The first chapter
briefly recalls some of the basic concepts in order to make this
book self-contained. Chapter two introduces the notion of set
vector spaces which is the most generalized concept of vector
spaces. Set vector spaces lends itself to define new classes of
vector spaces like semigroup vector spaces and group vector
6
spaces. These are also generalization of vector spaces. The
fuzzy analogue of these concepts are given in Chapter three.
In Chapter four, set vector spaces are generalized to biset
bivector spaces and not set vector spaces. This is done taking
into account the advanced information technology age in which
we live. As mathematicians, we have to realize that our
computer-dominated world needs special types of sets and
algebraic structures.
Set n-vector spaces and their generalizations are carried out
in Chapter five. Fuzzy n-set vector spaces are introduced in the
sixth chapter. The seventh chapter suggests more than three
hundred problems. When a researcher sets forth to solve them,
she/he will certainly gain a deeper understanding of these new
notions.

In this paper we study the notion of Smarandache
semirings and semifields and obtain some interesting results
about them. We show that not every semiring is a Smarandache
semiring. We similarly prove that not every semifield is a
Smarandache semifield. We give several examples to make the
concept lucid. Further, we propose an open problem about the
existence of Smarandache semiring S of finite order.

In this paper we study the Smarandache pseudo-ideals of a Smarandache ring. We
prove every ideal is a Smarandache pseudo-ideal in a Smarandache ring but every
Smarandache pseudo-ideal in general is not an ideal. Further we show that every
polynomial ring over a field and group rings FG of the group G over any field are
Smarandache rings. We pose some interesting problems about them.

This book is a continuation of the book n-linear algebra of type
I and its applications. Most of the properties that could not be
derived or defined for n-linear algebra of type I is made possible
in this new structure: n-linear algebra of type II which is
introduced in this book. In case of n-linear algebra of type II, we
are in a position to define linear functionals which is one of the
marked difference between the n-vector spaces of type I and II.
However all the applications mentioned in n-linear algebras of
type I can be appropriately extended to n-linear algebras of type
II. Another use of n-linear algebra (n-vector spaces) of type II is
that when this structure is used in coding theory we can have
different types of codes built over different finite fields whereas
this is not possible in the case of n-vector spaces of type I.
Finally in the case of n-vector spaces of type II we can obtain neigen
values from distinct fields; hence, the n-characteristic
polynomials formed in them are in distinct different fields.
An attractive feature of this book is that the authors have
suggested 120 problems for the reader to pursue in order to
understand this new notion. This book has three chapters. In the
first chapter the notion of n-vector spaces of type II are
introduced. This chapter gives over 50 theorems. Chapter two
introduces the notion of n-inner product vector spaces of type II,
n-bilinear forms and n-linear functionals. The final chapter
6
suggests over a hundred problems. It is important that the reader
should be well versed with not only linear algebra but also nlinear
algebras of type I.

With the advent of computers one needs algebraic structures
that can simultaneously work with bulk data. One such
algebraic structure namely n-linear algebras of type I are
introduced in this book and its applications to n-Markov chains
and n-Leontief models are given. These structures can be
thought of as the generalization of bilinear algebras and bivector
spaces. Several interesting n-linear algebra properties are
proved.
This book has four chapters. The first chapter just
introduces n-group which is essential for the definition of nvector
spaces and n-linear algebras of type I. Chapter two gives
the notion of n-vector spaces and several related results which
are analogues of the classical linear algebra theorems. In case of
n-vector spaces we can define several types of linear
transformations.
The notion of n-best approximations can be used for error
correction in coding theory. The notion of n-eigen values can be
used in deterministic modal superposition principle for
undamped structures, which can find its applications in finite
element analysis of mechanical structures with uncertain
parameters. Further it is suggested that the concept of nmatrices
can be used in real world problems which adopts fuzzy
models like Fuzzy Cognitive Maps, Fuzzy Relational Equations
and Bidirectional Associative Memories. The applications of
6
these algebraic structures are given in Chapter 3. Chapter four
gives some problem to make the subject easily understandable.

In this book we define the new notion of neutrosophic rings.
The motivation for this study is two-fold. Firstly, the classes of
neutrosophic rings defined in this book are generalization of the
two well-known classes of rings: group rings and semigroup
rings. The study of these generalized neutrosophic rings will
give more results for researchers interested in group rings and
semigroup rings. Secondly, the notion of neutrosophic
polynomial rings will cause a paradigm shift in the general
polynomial rings. This study has to make several changes in
case of neutrosophic polynomial rings. This would give
solutions to polynomial equations for which the roots can be
indeterminates. Further, the notion of neutrosophic matrix rings
is defined in this book. Already these neutrosophic matrixes
have been applied and used in the neutrosophic models like
neutrosophic cognitive maps (NCMs), neutrosophic relational
maps (NRMs) and so on.

Study of neutrosophic algebraic structures is very recent. The
introduction of neutrosophic theory has put forth a significant
concept by giving representation to indeterminates. Uncertainty or
indeterminacy happen to be one of the major factors in almost all
real-world problems. When uncertainty is modeled we use fuzzy
theory and when indeterminacy is involved we use neutrosophic
theory. Most of the fuzzy models which deal with the analysis and
study of unsupervised data make use of the directed graphs or
bipartite graphs. Thus the use of graphs has become inevitable in
fuzzy models. The neutrosophic models are fuzzy models that
permit the factor of indeterminacy. It also plays a significant role,
and utilizes the concept of neutrosophic graphs. Thus
neutrosophic graphs and neutrosophic bipartite graphs plays the
role of representing the neutrosophic models. Thus to construct
the neutrosophic graphs one needs some of the neutrosophic
algebraic structures viz. neutrosophic fields, neutrosophic vector
spaces and neutrosophic matrices. So we for the first time
introduce and study these concepts. As our analysis in this book is
application of neutrosophic algebraic structure we found it deem
fit to first introduce and study neutrosophic graphs and their
applications to neutrosophic models.

In this paper we introduce the concept of Smarandache non-associative rings,
which we shortly denote as SNA-rings as derived from the general definition of a
Smarandache Structure (i.e., a set A embedded with a week structure W such that a
proper subset B in A is embedded with a stronger structure S). Till date the concept of
SNA-rings are not studied or introduced in the Smarandache algebraic literature. The
only non-associative structures found in Smarandache algebraic notions so far are
Smarandache groupoids and Smarandache loops introduced in 2001 and 2002. But they
are algebraic structures with only a single binary operation defined on them that is nonassociative.
But SNA-rings are non-associative structures on which are defined two
binary operations one associative and other being non-associative and addition distributes
over multiplication both from the right and left. Further to understand the concept of
SNA-rings one should be well versed with the concept of group rings, semigroup rings,
loop rings and groupoid rings. The notion of groupoid rings is new and has been
introduced in this paper. This concept of groupoid rings can alone provide examples of
SNA-rings without unit since all other rings happens to be either associative or nonassociative
rings with unit. We define SNA subrings, SNA ideals, SNA Moufang rings,
SNA Bol rings, SNA commutative rings, SNA non-commutative rings and SNA
alternative rings. Examples are given of each of these structures and some open problems
are suggested at the end.

In this book we introduce the notion of Smarandache special
definite algebraic structures. We can also call them equivalently
as Smarandache definite special algebraic structures. These new
structures are defined as those strong algebraic structures which
have in them a proper subset which is a weak algebraic
structure. For instance, the existence of a semigroup in a group
or a semifield in a field or a semiring in a ring. It is interesting
to note that these concepts cannot be defined when the algebraic
structure has finite cardinality i.e., when the algebraic structure
has finite number of elements in it.

Graphs and matrices play a vital role in the analysis
and study of several of the real world problems which
are based only on unsupervised data. The fuzzy and
neutrosophic tools like fuzzy cognitive maps invented
by Kosko and neutrosophic cognitive maps introduced
by us help in the analysis of such real world problems
and they happen to be mathematical tools which can
give the hidden pattern of the problem under
investigation. This book, in order to generalize the two
models, has systematically invented mathematical
tools like bimatrices, trimatrices, n-matrices, bigraphs,
trigraphs and n-graphs and describe some of its
properties. These concepts are also extended
neutrosophically in this book.

Matrix theory has been one of the most utilised concepts in
fuzzy models and neutrosophic models. From solving
equations to characterising linear transformations or linear
operators, matrices are used. Matrices find their applications
in several real models. In fact it is not an exaggeration if
one says that matrix theory and linear algebra (i.e. vector
spaces) form an inseparable component of each other.

While I began researching for this book on linear algebra, I was a little startled.
Though, it is an accepted phenomenon, that mathematicians are rarely the ones to
react surprised, this serious search left me that way for a variety of reasons. First,
several of the linear algebra books that my institute library stocked (and it is a really
good library) were old and crumbly and dated as far back as 1913 with the most 'new'
books only being the ones published in the 1960s.

In 1965, Lofti A. Zadeh introduced the notion of a fuzzy subset of a set as
a method for representing uncertainty. It provoked, at first (and as
expected), a strong negative reaction from some influential scientists and
mathematicians - many of whom turned openly hostile. However, despite
the controversy, the subject also attracted the attention of other
mathematicians and in the following years, the field grew enormously,
finding applications in areas as diverse as washing machines to
handwriting recognition. In its trajectory of stupendous growth, it has also
come to include the theory of fuzzy algebra and for the past five decades,
several researchers have been working on concepts like fuzzy semigroup,
fuzzy groups, fuzzy rings, fuzzy ideals, fuzzy semirings, fuzzy near-rings
and so on.

The study of bialgebraic structures started very recently. Till date there are no books
solely dealing with bistructures. The study of bigroups was carried out in 1994-1996.
Further research on bigroups and fuzzy bigroups was published in 1998. In the year
1999, bivector spaces was introduced. In 2001, concept of free De Morgan
bisemigroups and bisemilattices was studied. It is said by Zoltan Esik that these
bialgebraic structures like bigroupoids, bisemigroups, binear rings help in the
construction of finite machines or finite automaton and semi automaton. The notion of
non-associative bialgebraic structures was first introduced in the year 2002. The
concept of bialgebraic structures which we define and study are slightly different from
the bistructures using category theory of Girard's classical linear logic. We do not
approach the bialgebraic structures using category theory or linear logic.

An associative ring is just realized or built using reals or complex; finite or infinite
by defining two binary operations on it. But on the contrary when we want to define
or study or even introduce a non-associative ring we need two separate algebraic
structures say a commutative ring with 1 (or a field) together with a loop or a
groupoid or a vector space or a linear algebra. The two non-associative well-known
algebras viz. Lie algebras and Jordan algebras are mainly built using a vector space
over a field satisfying special identities called the Jacobi identity and Jordan identity
respectively. Study of these algebras started as early as 1940s. Hence the study of
non-associative algebras or even non-associative rings boils down to the study of
properties of vector spaces or linear algebras over fields.

Near-rings are one of the generalized structures of rings. The study and research on
near-rings is very systematic and continuous. Near-ring newsletters containing
complete and updated bibliography on the subject are published periodically by a
team of mathematicians (Editors: Yuen Fong, Alan Oswald, Gunter Pilz and K. C.
Smith) with financial assistance from the National Cheng Kung University, Taiwan.
These newsletters give an overall picture of the research carried out and the recent
advancements and new concepts in the field. Conferences devoted solely to near-rings
are held once every two years. There are about half a dozen books on near-rings apart
from the conference proceedings. Above all there is a online searchable database and
bibliography on near-rings. As a result the author feels it is very essential to have a
book on Smarandache near-rings where the Smarandache analogues of the near-ring
concepts are developed. The reader is expected to have a good background both in
algebra and in near-rings; for, several results are to be proved by the reader as an

The study of Smarandache Algebraic Structure was initiated in the year 1998 by Raul
Padilla following a paper written by Florentin Smarandache called "Special Algebraic
Structures". In his research, Padilla treated the Smarandache algebraic structures mainly with
associative binary operation. Since then the subject has been pursued by a growing number of
researchers and now it would be better if one gets a coherent account of the basic and main
results in these algebraic structures. This book aims to give a systematic development of the
basic non-associative algebraic structures viz. Smarandache groupoids. Smarandache
groupoids exhibits simultaneously the properties of a semigroup and a groupoid. Such a
combined study of an associative and a non associative structure has not been so far carried
out. Except for the introduction of smarandacheian notions by Prof. Florentin Smarandache
such types of studies would have been completely absent in the mathematical world.

In this book, the authors define several new types of soft neutrosophic algebraic structures over neutrosophic algebraic structures and we study their generalizations. These soft neutrosophic algebraic structures are basically parameterized collections of neutrosophic sub-algebraic structures of the neutrosophic algebraic structure. An important feature of this book is that the authors introduce the soft neutrosophic group ring, soft neutrosophic semigroup ring with its generalization, and soft mixed neutrosophic N-algebraic structure over neutrosophic group ring, then the neutrosophic semigroup ring and mixed neutrosophic N-algebraic structure respectively.

In this paper we prove the Generalized Continuum Hypothesis, which is, as Universal Algebra and Category Theory, a complete theory, proving that
the infinite initial ordinals and the transfinite cardinals are isomorphic universal algebras.
For isomorphic universal algebras are isomorphic categories, isomorphic categories are isomorphic theories, by the Fundamental Theorem of Categorical Logic, and so, isomorphic universal algebras are isomorphic theories.

During the 360 years of Fermat's last theorem is to be proved, this proposition
was the presence appear full-length novel in "The Lord of the Rings", such as
the "One Ring". And finally in 1994, it was proved completely by Andrew
Wiles. However interesting proof is Fermat has been is still unknown. This will
be assumed in the category of algebra probably.

The algebraic structures built using [0, n) interval are new and innovative. They happen to have different properties. The interval [0, n) can be realized as the real algebraic closure of the modulo ring Zn. The algebraic behavior of [0, n) is different from the ring Zn.

**Comments:** There are 6 Pages, 6 Theorems, 7 Figures. I also made a small correction that in Theorem-1, the correct word is "NP-Hard" and not "NP-Complete".

We convert, within polynomial-time and sequential processing, an NP-Complete Problem into a real variable problem of minimizing a sum of Rational Linear Functions constrained by an Asymptotic-Linear-Program. The coefficients and constants in the real-variable problem are 0, 1, -1, K, or -K, where K is the time parameter that tends to positive infinity. The number of variables, constraints, and rational linear functions in the objective, of the real-variable problem is bounded by a polynomial function of the size of the NP-Complete Problem. The NP-Complete Problem has a feasible solution, if-and-only-if, the real-variable problem has a feasible optimal objective equal to zero. We thus show the strong NP-hardness of this real-variable optimization problem.

The authors in this book have analyzed the socio-economic and
psychological problems faced by People with Disabilities
(PWDs) and their families. The study was made by collecting
data using both fuzzy linguistic questionnaire / by interviews in
case they are not literates from 2,15,811 lakhs people. This data
was collected using the five Non Government Organizations
(NGOs) from northern Tamil Nadu.

Using a personal computer and freely available software, the author
factored some members of the Smarandache consecutive sequence and
the reverse Smarandache sequence. Nearly complete factorizations are
given up to Sm(80) and RSm(80). Both sequences were excessively
searched for prime members, with only one prime found up to Sm(840)
and RSm(750): RSm(82) = 828180 ... 10987654321.
