Since the world is full of indeterminacy, the neutrosophics found their place into
contemporary research. In this paper we define rough neutrosophic sets and study their
properties. Some propositions in this notion are proved. Possible application to computer

Let $U^{(n)}$ denote the maximal length arithmetic
progression in a non-uniform random subset of $\{0,1\}^n$, where $1$
appears with probability $p_n$. By using dependency graph and
Stein-Chen method, we show that $U^{(n)}-c_n\ln n$ converges in law
to an extreme type distribution with $\ln p_n=-2/c_n$. Similar
result holds for $W^{(n)}$, the maximal length aperiodic arithmetic
progression (mod $n$).

There was an attempt to formalize an appearance of main relation properties in contrast to the usual one. There were paid an attention only for natural relations. Surely, such relations as “better than” are not observed here since the notion of “good” itself is still not defined.

Standard mathematics involves such notions as infinitely small/large, continuity and standard division. However, some of these notions are treated differently in traditional and constructive versions. This mathematics is usually treated as fundamental while finite mathematics is treated as inferior. Standard mathematics has foundational problems (as follows, for example, from G\"{o}del's incompleteness theorems) but people usually believe that this is less important than the fact that it describes many experimental data with high accuracy. We argue that the situation is the opposite: standard mathematics is only a special case of finite one in the
formal limit when the characteristic of the ring or field used in finite mathematics goes to infinity. Therefore foundational problems
in standard mathematics are not fundamental.

If B(P) is the truth value of proposition P then connectives could be translated to arithmetic operation in the congruent expression of 2 as described below.
B(~p)≡1+B(p)( mod 2 ),B(p∧q)≡B(p)B(q)( mod 2 )
B(p∨q)≡B(p)+B(q)+B(p)B(q)( mod 2 )
B(p⟶q)≡1+B(p)+B(p)B(q)( mod 2 )
B(p⟷q)≡1+B(p)+B(q)(mod 2)
By using this, logical laws could be proved, compound proposition could be simplified, and logical equation could be solved.

This paper introduces a new type of set called the Sohraab-Hyder set or the SH set which is quite different from the well known and studied set of the Set Theory. This new set theory is logically consistent and leads to some fascinating results such as, (1) the necessary existence of an ultimate SH set that created itself in pre-eternity and will continue to exist to post-eternity, (2) the ultimate SH set is self sufficient, (2) the ultimate SH set must give rise to infinite number of other SH sets which represent logically consistent algebras and geometries, (3) the ultimate SH set must give rise to the existence of infinite universes, including our own, (4) the ultimate SH set must give rise to mathematical cells, organs and organisms which undergo must undergo evolution, (5) some of these mathematical cells, organs and organisms are same as the organic cells, organs and organisms which leads to the conclusion that the evolution of organisms is a mathematical fact and finally, (6) it is shown that every living and non-living entity in the universe, with the universe included of course, is a matrix of 0's and 1's.

In 1963, nonstandard analysis was applied to the semantics of formal languages. In 1978, nonstandard analysis was first applied to the syntax of formal and informal languages via the notion of the consequence operator (operation) and later the logic-system. In order to incorporate both of these approaches into the Theory of Ultralogics, a foundational change is necessary.

It is proved in this paper the undecidable formula involved in Gödel's first incompleteness theorem would be inconsistent if the formal system where it is defined were complete. So, before proving the formula is undecidable it is necessary to assume the system is not complete in order to ensure the formula is not inconsistent. Consequently, Gödel proof does not prove the formal system is incomplete but that, once assumed it is incomplete, it is possible to define an undecidable formula within the system. This conclusion makes Gödel's incompleteness theorems devoid of substance.

In this paper we present a short history of logics: from particular cases of 2-symbol or numerical
valued logic to the general case of n-symbol or numerical valued logic. We show generalizations
of 2-valued Boolean logic to fuzzy logic, also from the Kleene’s and Lukasiewicz’ 3-symbol
valued logics or Belnap’s 4-symbol valued logic to the most general n-symbol or numerical
valued refined neutrosophic logic. Two classes of neutrosophic norm (n-norm) and neutrosophic
conorm (n-conorm) are defined. Examples of applications of neutrosophic logic to physics are
listed in the last section.
Similar generalizations can be done for n-Valued Refined Neutrosophic Set, and respectively n-
Valued Refined Neutrosopjhic Probability.

Relative to universal logic, it is demonstrated how useful it is to utilize general logic-systems to investigate finite consequence operators (operations). Among many other examples relative to the lattice of finite consequence operators, a general characterization for the lattice-theoretic supremum for a nonempty collection of finite consequence operators is given. Further, it is shown that for any denumerable language there is rather simple collection of finite consequence operators and for a propositional language, three simple modifications to the finitary rules of inference that demonstrate that the lattice of finite consequence operators is not meet-complete.

The First International Conference on Smarandache Multispace and Multistructure was organized by Prof. Linfan Mao, and it was held in the Beijing University of Civil Engineering and Architecture of P. R. China on June 28-30, 2013. There were 46 researchers from China, India, Iran, Nigeria, and USA that have taken part in this conference with 14 papers on Smarandache multispace and geometry, birings, neutrosophy,neutrosophic groups, regular maps and topological graphs with applications to non-solvable equation systems.
Definition.
In any domain of knowledge, a Smarandache multispace (or S-multispace) with its multistructure is a finite or infinite (countable or uncountable) union of many spaces that have various
structures. The spaces may overlap. The notions of multispace (also spelt multi-space) and multi-
structure (also spelt multi-structure) were introduced by Smarandache in 1969 under his idea of hybrid science: combining different fields into a unifying field, which is closer to our real life world since we live in a heterogeneous space. Today, this idea is widely accepted by the world of sciences. S-multispace is a qualitative notion, since it is too large and includes both metric and non-metric spaces. It is believed that the smarandache multispace with its multistructure is the best candidate for 21st century Theory of Everything in any domain. It unifies many knowledge fields.
Applications.
A such multispace can be used for example in physics for the Unified Field Theory that tries to unite the gravitational, electromagnetic, weak and strong interactions. Or in the parallel quantum computing and in the mu-bit theory, in multi-entangled states or particles and up to multi-entangles objects. We also mention: the algebraic multispaces (multi-groups, multi-rings, multi-vector spaces, multi-operation systems and multi-manifolds, also multi-voltage graphs, multi-embedding of a graph in an n-manifold, etc.), geometric multispaces (combinations of Euclidean and Non-Euclidean geometries into one space as in Smarandache geometries), theoretical physics, including the relativity theory, the M-theory and the cosmology, then multi-space models for p-branes and cosmology, etc.
- The multispace and multistructure were first used in the Smarandache geometries (1969), which are combinations of different geometric spaces such that at least one geometric axiom behaves differently in each such space.
- In paradoxism (1980), which is a vanguard in literature, arts, and science, based on finding
common things to opposite ideas [i.e. combination of contradictory fields].
- In neutrosophy (1995), which is a generalization of dialectics in philosophy, and takes into con-
sideration not only an entity < A > and its opposite < antiA > as dialectics does, but also the
neutralities < neutA > in between. Neutrosophy combines all these three < A >,< antiA > and
< neutA > together. Neutrosophy is a metaphilosophy.
- Then in neutrosophic logic (1995), neutrosophic set (1995), and neutrosophic probability (1995), which have, behind the classical values of truth and falsehood, a third component called indeterminacy (or neutrality, which is neither true nor false, or is both true and false simultaneously - again a combination of opposites: true and false in indeterminacy).
- Also used in Smarandache algebraic structures (1998), where some algebraic structures are in-
cluded in other algebraic structures.

The concept of ultra-universal algebras in varieties is generalized to models of first order theories. Characterizations of theories which have ulta-universal models are found and general examples of ultra-universal models are investigated. In particular we show that a theory has an ultra-universal model iff it is consistent and its class of models satisfies the joint embedding property.

This paper will demonstrate a diagonal argument by listing all non-empty finite ordinals in a table according to their ε order using their subset representation, meaning {0,1,2…n-1} is listed for the ordinal n. Next, the axiom of choice is applied to all of these ordinals and selects the maximal element. This selection process forms a diagonal which satisfies the axiom of infinity, hence, the diagonal is a limit ordinal. However, it will also be shown for the nth choice made by the choice function, the diagonal is the successor ordinal number n = {0,1,2…n-1} and this is true for all n. So, at the n+1 choice, the diagonal is the ordinal n+1 and so on. Therefore, based on all the actions of the choice function, it is provable from ZFC on one hand that this diagonal cannot ever be anything other than a successor ordinal and on the other hand, the diagonal is a limit ordinal.

If there is something I am not explaining very elaborately or descriptively, let me know. I have had a math professor who showed me her inconsistent equations saying "these equations have no solution" although my equations are consistent and homogeneous which always have a solution. Also, I have had another math professor who told me it is wrong to assign specific values to variables although I was assigning factor variables to composite variables not to mention how there is an underlying condition how these numbers are positive integers excluding zero.
In this paper, I am creating a new theorem called Victoria Hayanisel Theorem dedicated to Princess Eugenie of York to describe the state of numbers, circles, and lines.
Followed by the theorem, I am using the set theory and Fermat's Infinite Descent Method (if my method is different, I will name it) to show how the conjecture is true.

The debate between process infinity and Cantor’s eigentlich Unendliche “completed infinity” has occurred since before Greek times. Prior to Cantor, the prevailing view of infinity was that it is a process that continues on forever and there is only one type of infinity. Cantor, on the other hand, produced the current foundations of mathematics with his hierarchy of completed infinite objects. In particular, the completed infinite set ω contains all natural numbers and none are missing from the set. This paper will demonstrate, however, a specific method under ZFC of assembling all finite ordinals into the completed set ω such that ω ε ω is a necessary condition of that formation. Then, from ω ε ω, it will be shown ZFC is inconsistent.

It is the underlying purpose of the author throughout this and subsequent related

both autonomous and presented herein, that it may become evident that the introduction
of fundamental, new practices is a necessity to any advancement in the directions of the
aforementioned. This represents the first in a series of eight (8) papers regarding these
materials. Throughout the remaining 7 the author presents, to a much greater degree of
rigor, the basic theory of analytic gauge functions, associated phenomenology, and there
from a solution to the (two) above conjectures. This paper facilitates an introduction to
the theory of analytic gauges. In the first section the author presents a re-examination of
the concepts of geometries of connections. Very briefly introduced are the basic concepts
of analytic numbers, analytic fields, analytic gauge functions, etc.

hyperrational-valued, hyperreal-valued, and p-adic valued logics characterized
by a special format of semantics with an appropriate rejection
of Archimedes' axiom. These logics are built as different extensions of
standard many-valued logics (namely, Lukasiewicz's, Gödel's, Product,
and Post's logics). The informal sense of Archimedes' axiom is that anything
can be measured by a ruler. Also logical multiple-validity without
Archimedes' axiom consists in that the set of truth values is infinite and
it is not well-founded and well-ordered. We consider two cases of
non-Archimedean multi-valued logics: the first with many-validity in the interval
[0; 1] of hypernumbers and the second with many-validity in the
ring Zp of p-adic integers. On the base of non-Archimedean valued logics,
we construct non-Archimedean valued interval neutrosophic logics by
which we can describe neutrality phenomena.

This paper outlines an approach to mathematical logic which is different from the standard one. We
list the most relevant features of the system. In first-order logic there exist two different concepts of
term and formula, in place of these two concepts in our approach we have just one notion of
expression. The set-builder notation is enclosed as an expression-building pattern. In our system we
can easily express second-order and all-order conditions (the set to which a quantifier refers is
explicitly written in the expression). The meaning of a sentence will depend solely on the meaning
of the symbols it contains, it will not depend on external 'structures'. Our deductive system is based
on a very simple definition of proof and provides a good model of human mathematical deductive
process. The soundness and consistency of the system are proved, as well as the fact that our system
is not affected by the most known types of paradox. The paper provides both the theoretical
material and two fully documented examples of deduction. The author has built the whole system
with the idea to provide a faithful model of human mathematical deductive process. He believes this
objective has been achieved but obviously the reader is free to examine the system and get his own
opinion about it.

A paradox is called a statement <P> which is true and false in the same time.
Therefore, if we suppose that statement <P> is true, it results that <P> is false; and reciprocally,
if we suppose that <P> is false, it results that <P> is true.

It was a surprise for me when in 1995 I received a manuscript from the mathematician,
experimental writer and innovative painter Florentin Smarandache, especially because the
treated subject was of philosophy - revealing paradoxes - and logics.
He had generalized the fuzzy logic, and introduced two new concepts:
a) "neutrosophy" - study of neutralities as an extension of dialectics;
b) and its derivative "neutrosophic", such as "neutrosophic logic", "neutrosophic set",
"neutrosophic probability", and "neutrosophic statistics" and thus opening new ways
of research in four fields: philosophy, logics, set theory, and probability/statistics.

This book written by A. Schumann & F. Smarandache is devoted to advances
of non-Archimedean multiple-validity idea and its applications to logical reasoning.
Leibnitz was the first who proposed Archimedes' axiom to be rejected.
He postulated infinitesimals (infinitely small numbers) of the unit interval [0, 1]
which are larger than zero, but smaller than each positive real number. Robinson
applied this idea into modern mathematics in [117] and developed so-called
non-standard analysis. In the framework of non-standard analysis there were
obtained many interesting results examined in [37], [38], [74], [117].

I claim that Neutrosophy, by Professor Florentin Smarandache, is a deep thought in human culture.
That gives advantage to break the mechanical understanding of human culture. For example,
according to the mechanical theory: existence and non-existence could not be simultaneously.
Actually existence and non-existence are simultaneously. Everyone knows that human life is
like a way in the empty space of a bird flying. Everyone can not see himself a second ago,
everyone can not see himself for the time being and everyone can not see himself a second
future. Everyone could not know what is the existence of self. Everyone is also difficult to
say the non-existence of self. So the existence and non-existence of self are simultaneously.
And the existence and nonexistence of everything are simultaneously, where, the law of excluded
middle does not apply. These basic facts express the depth of Smarandache's Neutrosophy. He
has a lot of friends in ancient and in nowadays, in the West and in the East.

Logic should have been defined as the unity of contradiction between logic director and logic
implementation. Chinese Daoism asserts that everything is defined in the unity of opposites,
namely yin and yang, accordingly yang conducts change and yin brings it up (I-Ching, also known
as Book of Changes). In this way logic is redefined in an indeterminate style to facilitate
"both A and Anti-A" etc. in neutrosophics of logic. The unity of opposites is also described
as neutrality in neutrosophy. An intermediate multi-referential model of excitation and inhibition
is developed to derive a multiagent architecture of logic, based on Chinese yin-yang philosophy.
This methodology of excitation/inhibition suggests a rhymed way of logic, leading to a dynamic
methodology of weight strategy that links logic with neural network approach. It also confirms
the crucial role of indeterminacy in logic as a fatal criticism to classical mathematics and
current basis of science.

As a philosophical analysis of some fatal paradoxes, the paper distinguishes the conceptual difference
between representation of truth and source of truth, and leads to the conclusion that in order to acquire
the genuine source of truth, independently of specific representations possibly belonging to different
worlds, one is necessary to ignore all the ideas, logics, conceptions, philosophies and representable
knowledge even himself belonging to those misleading worlds, returning to his infant nature, as a
preliminary step for his cultivation of unconstrained wisdom. It also carries out some coordinative
crucial issues as natural-doctrine, minded-unwitting, logic-infancy, conception-deconception,
determinacy-indeterminacy. The paper tries to verify the role of neutrosophy and neutrosophic logic in
religious issues and open a gateway toward the oriental classics, excavating the lost treasure.

Neutrosophic set is a part of neutrosophy which
studies the origin, nature, and scope of neutralities, as
well as their interactions with different ideational
spectra. Neutrosophic set is a powerful general formal
framework that has been recently proposed. However,
neutrosophic set needs to be specified from a technical
point of view. To this effect, we define the settheoretic
operators on an instance of neutrosophic set,
we call it single valued neutrosophic set (SVNS). We
provide various properties of SVNS, which are
connected to the operations and relations over SVNS.

These paradoxes are called "neutrosophic" since they are based on indeterminacy (or neutrality,
i.e. neither true nor false), which is the third component in neutrosophic logic. We generalize the
Venn Diagram to a Neutrosophic Diagram, which deals with vague, inexact, ambiguous, illdefined
ideas, statements, notions, entities with unclear borders. We define the neutrosophic truth
table and introduce two neutrosophic operators (neuterization and antonymization operators)
give many classes of neutrosophic paradoxes.

The paper presents an initial explorations on T, I, F operations based on genetic concept
hierarchy and genetic referential hierarchy, as a novel proposal to the indeterminacy issue in
neutrosophic logic, in contrast to the T, I, F values inherited from conventional logics in which
those values would fail to demonstrate the genetic aspect of a concept and accordingly loose the
connection between generality and practicality. Based on the novel definition of logic and on the
relativity of T, F concept, it illustrates that T, F are hierarchical operations which inter-consist and
inter-complement each other, that "I" relates to a learning behavior profiled by an inspiration from
I-ching, and that the neutralization operation, as the means to solve contradictions, will eventually
come to the unification of opposites, leading to the fundamental issues in Buddhism and such alike.
It also implies that Buddhism and Daoism are not religions.

Based on the authors intensive investigation on the oriental dialectics, the paper presents a novel
theoretical frame of matter element in the world leading science, extenics dealing with inconsistency or
incompatibility, covering the widest range of application area from informatics, system engineering to
management and finance. The dialectic matter-element is defined as the integral of all existing and prospecting
ones based on all the infinite possible cognitive models. The novel model serves as the origin of constraint
matter elements, the unity of both state description and cognitive action (cognition force with respect to neural
science), a latent part of extenics, and possibly as essence of matter element. It explains, in a novel perspective,
the origin of a name, and uncovers the source of contradiction and even the impetus of cognition.

The paper presents a fresh new comprehensive ideology on Neutrosophic Logic based
on contradiction study in a broad sense: general critics on conventional logic by examining the essence of
logic, fresh insights on logic definition based on Chinese philosophical survey, and a novel and genetic
logic model as the elementary cell against Von Neumann oriented ones based on this novel definition. As
for the logic definition, the paper illustrates that logic is rather a tradeoff between different factors than
truth and false abstraction. It is stressed that the kernel of any intelligent system is exactly a contradiction
model. The paper aims to solve the chaos of logic and exhibit the potential power of neutrosophy: a new
branch of scientific philosophy.

The paper presents a fresh new start on the neutrality of neutrosophy in
that "both A and Non-A" as an alternative to describe Neuter-A in that we conceptualize
things in both intentional and unintentional background. This unity of opposites
constitutes both objective world and subjective world. The whole induction of such
argument is based on the intensive study on Buddhism and Daoism including I-ching. In
addition, a framework of contradiction oriented learning philosophy inspired from the
Later Trigrams of King Wen in I-ching is meanwhile presented. It is shown that although
A and Non-A are logically inconsistent, but they are philosophically consistent in the
sense that Non-A can be the unintentionally instead of negation that leads to confusion. It
is also shown that Buddhism and Daoism play an important role in neutrosophy, and
should be extended in the way of neutrosophy to all sciences according to the original
intention of neutrosophy.

The set of all the subsets of a set is its power set, and the cardinality of the power set is always larger than the set and its subsets. Based on the definition and the inequality in cardinality, a set cannot include its power set as element, and a power set cannot include itself as element. "Russell's set" is a putative set of all the sets that don't include themselves as element. It can be shown, however, that "Russell's set" can never take in all such sets. This is because its own power set, which (like any power set) is a set that doesn't include itself (thus qualifies as an element for "Russell's set"), cannot (although should) be taken in due to the cardinality inequality. Thus "Russell's set" can never be formed. Without it, Russell's paradox, which forced the modification of Cantor's intuitive set theory into a more restricted axiomatic theory, can never be formulated. The reported approach to resolve Russell's paradox is fundamentally different from the conventional approaches. It may restore the self-consistency of Cantor's original set theory, make the Axiom of Regularity unnecessary, and expand the coverage of set to assemblies that include themselves as element.

In 1949, Gödel postulated a theorem that stated: "In any universe described by the theory of relativity,
time cannot exist". Gödel idea was that forth coordinate of space-time is not time. Fourth coordinate is
spatial too. In this article will be shown that on the base of elementary perception and experimental data
Gödel theorem is right. With eyes one observes universe is in a continuous change. A change n gets
transformed into a change n+1, the change n+1 into a change n+2 and so on. Clocks measure a
frequency, velocity and numerical order of change. Experimental date confirms that changes and clocks
do not run time; they run in space only. Time is not a part of space. Fourth coordinate of space-time is
spatial too. Space itself is timeless. Physical time that is clocks run is man created physical reality.
Fundamental arena of the universe is timeless space. In the timeless space into which massive bodies
and elementary particles move there is no past and no future. Past and future belong to the inner
neuronal space-time that is a result of neuronal activity of the brain.

Standard mathematics involves such notions as infinitely small/large, continuity and standard division. This mathematics is usually treated as fundamental while finite mathematics is treated as inferior. Standard mathematics has foundational problems (as follows, for example, from G\"{o}del's incompleteness theorems) but it is usually believed that this is less important than the fact that it describes many experimental data with high accuracy. We argue that the situation is the opposite: standard mathematics is only a degenerate case of finite one in the formal limit when the characteristic of the ring or field used in finite mathematics goes to infinity. Therefore foundational problems in standard mathematics are not fundamental.

In this paper we prove the continuum hypothesis with categorical mathematical logic by proving that the theory of initial ordinals and the theory of cardinals are isomorphic. We use the definition of a theory, the fact that isomorphic structures are isomorphic theories known as the fundamental theorem of mathematical logic, the definition of an isomorphism of structures, in its equivalent form, the definition of an isomorphism of categories, the definition of a structure, the definition of a formal language, the definition of a functor, the definition of a category, the axioms of mathematical logic, and the axioms of the theory of categories, which include the Gödel-Bernays-von Neumann axioms for classes and sets. And thus, applying both the theorem of comparablity of ordinals to the theory of cardinals, and the fundamental theorem of cardinal arithmetic to the theory of ordinals, we prove the theorem.

In this paper we give the N-th root algorithm in completions of fraction semfields of normed euclidean semialgebras for every natural N > 1. The algorithm starts with a nonzero element of arbitrary length n in terms of its p-adic expansion for a nonunit p of nonzero degree of a normed euclidean semialgebra, thereafter, for a nonzero natural m = O(n), writes O(m) elements of length O(1) to go through O(m) steps in each of which compares, calculates and writes O(1) elements of length O(m^(N-1)), and so, in time O(n^N).

The paper is about an approach to logic that differs from the standard first-order logic and other known approaches. It should be a new approach the author has created proposing to obtain a general and unifying approach to logic and a faithful model of human mathematical deductive process. We list the most relevant features of the system. In first-order logic there exist two different concepts of term and formula, in place of these two concepts in our approach we have just one notion of expression. The set-builder notation is enclosed as an expression-building pattern. In our system we
can easily express second-order and all-order conditions (the set to which a quantifier refers is explicitly written in the expression). The meaning of a sentence will depend solely on the meaning of the symbols it contains, it will not depend on external `structures'. Our deductive system is based on a very simple definition of proof and provides a good model of human mathematical deductive process. The soundness and consistency of the system are proved, as well as the fact that our system is not affected by the most known types of paradox. The paper provides both the theoretical material and two fully documented examples of deduction. The author believes his aims have been achieved, obviously the reader is free to examine the system and get his own opinion about it.

These paradoxes are called "neutrosophic" since they are based on indeterminacy (or neutrality,
i.e. neither true nor false), which is the third component in neutrosophic logic. We generalize the
Venn Diagram to a Neutrosophic Diagram, which deals with vague, inexact, ambiguous, illdefined
ideas, statements, notions, entities with unclear borders. We define the neutrosophic truth
table and introduce two neutrosophic operators (neuterization and antonymization operators)
give many classes of neutrosophic paradoxes.
