ABSTRACT
The Riemann Hypothesis is a proposal given by Bernhard Riemann in 1859 that the non-trivial zeros of the Riemann zeta function all have real part ½ or .5. The conjecture is that all the non-trivial zeros lie along the critical line.

In this work I am going to mention historical development of divergent series theory, and to give a number of different examples, as some of the methods for their summing. After that, I am going to introduce the general method, which I discovered, for summing divergent series, which we can also consider as a method for computing limits of divergent sequences and functions in divergent points, In this case, limits of sequences of their partials sums. Through the exercises, I am going to apply this method on given examples and prove its validity. Then I'm going to apply the method to compute the value of some divergent integrals.

The reference [2] contructs the Operator axioms to deduce number systems. In this paper, we slightly improve on the syntax of the Operator axioms and construct a semantics of the Operator axioms. Then on the basis of the improved Operator axioms, we define two fundamental operator functions to study the analytic properties of the Operator axioms. Finally, we prove two theorems about the fundamental operator functions.

We consider (strong uniform) continuity of the
limit of a pointwise convergent net of lattice
group-valued functions, (strong weak)
exhaustiveness and (strong)
alpha-convergence with respect to a pair
of filters, which in the setting of nets are
more natural than the corresponding notions
formulated with respect to a single filter. Some
comparison results are given between such concepts, in connection with suitable properties of filters. Moreover, some modes of filter
(strong uniform) continuity for lattice
group-valued functions are investigated, giving
some characterization. As an application, we get
some Ascoli-type theorem in an abstract setting,
extending earlier results to the context of filter
alpha-convergence.

We show how real and complex Fourier transforms
are extended to W.R. Hamilton's algebra of quaternions and to
W.K. Clifford’s geometric algebras. This was initially motivated by
applications in nuclear magnetic resonance and electric engineering.
Followed by an ever wider range of applications in color image and
signal processing. Clifford's geometric algebras are complete algebras,
algebraically encoding a vector space and all its subspace elements.
Applications include electromagnetism, and the processing of images,
color images, vector field and climate data. Further developments of
Clifford Fourier Transforms include operator exponential representations,
and extensions to wider classes of integral transforms, like
Clifford algebra versions of linear canonical transforms and wavelets.

In the recent paper {\it Communications in Nonlinear Science and Numerical Simulation.
Vol.18. No.11. (2013) 2945-2948}, it was demonstrated that a violation of the Leibniz rule is a characteristic property
of derivatives of non-integer orders.
It was proved that all fractional derivatives ${\cal D}^{\alpha}$,
which satisfy the Leibniz rule
${\cal D}^{\alpha}(fg)=({\cal D}^{\alpha}f) \, g + f \, ({\cal D}^{\alpha}g)$,
should have the integer order $\alpha=1$, i.e.
fractional derivatives of non-integer orders cannot satisfy the Leibniz rule. However, it should be noted that this result is only for differentiable functions.
We argue that the very reason for introducing
fractional derivative is to study non-differentiable functions.
In this note, we try to clarify and summarize the Leibniz rule for both differentiable and non-differentiable functions. The Leibniz rule holds for differentiable functions with classical integer order derivative. Similarly the Leibniz rule still holds for non-differentiable functions with a concise and essentially local
definition of fractional derivative. This could give a more unified picture and understanding for Leibniz rule and the geometrical interpretation for both integer order and fractional derivative.

Gaussian integrals appear frequently in mathematics and physics, especially probability, statistics and quantum mechanics. One of the truly odd things about these integrals is that they cannot be evaluated in closed form over finite limits but are generally exactly integrable over +/- infinity. Yet their evaluation is still often difficult, particularly multi-dimensional integrals and those involving quadratics, vectors and matrices in the exponential. An added complication is that Gaussian integrals can involve ordinary real or complex variables as well as the less familiar Grassmann variables, which are important in the description of fermions. In this elementary primer
we present some of the more common Gaussian integrals of both types, along with methods for their evaluation.

Korovkin-type theorems with respect to

We give a unified approach, by

This paper briefly reviews the notion of Clifford's geometric algebras and vector to multivector functions; as well as the field of Clifford analysis (function theory of the Dirac operator). In Clifford Fourier transformations (CFT) on multivector signals the complex unit $i\in \mathbb{C}$ is replaced by a multivector square root of $-1$, which may be a pseudoscalar in the simplest case. For these transforms we derive, via a multivector function representation in terms of monogenic polynomials, the operator representation of the CFTs by exponentiating the Hamilton operator of a harmonic oscillator.

Crowds are generally analyzed in the regime of sociology- where
they are studied and classified on the basis of crowd psychology.
This analysis arises from the study of collective behavior and treats
crowds as dependent on psychology of humans in the crowd. In this
introductory paper we show a generalized treatment of crowds as a
set of living objects: called members of the crowd. We classify
crowds based on various parameters and study some general and
specific characteristics of crowd of humans and study the response
of a simple crowd to an external situation or stimulus by deriving the
solution of the generalized crowd equation. We also define some
terminology regarding the mathematical description of crowds and
hence arrive at some useful conjectures.

ABSTRACT:
Objective:
The purpose of this article is to express mathematically all the available information about any chronic neurological disease, such as relapsing-remitting multiple sclerosis, in such a way that all the known variables of the disease can be expressed as a function with time as one of the variables and thereby follow the disease in real time both generally and specifically in a given patient.
Methods:
The method consists of mapping all the known variables about any chronic neurological disease, such as relapsing-remitting multiple sclerosis on a (n+1) dimensional space with time being one of the variables and deriving from this certain functions that represent the disease generally and also specifically in any given patient.
Results:
The results of using this method is the derivation of functions with (n+1) variables. One of the functions will represent the entire disease generically, while other functions will represent the disease in any given individual patient.
Conclusions:
Using this method one can derive several conclusions. These include, finding any sub-types of a chronic neurological disease, help in the prognostication of the disease course in a given patient, stratification of the treatments for the disease, selection of a treatment that is the most useful for a given patient and finally remove the need for doing long and expensive head to head clinical trials of the different treatments for a disease.

As it will turn out in this paper, the recent hype about most of the Clifford Fourier transforms is not worth the pain.
Almost every one that has a real application is separable and these transforms can be decomposed into a sum of real valued
transforms with constant multivector factors. This fact makes their interpretation, their analysis and their implementation
almost trivial.

Conformal geometric algebra is preferred in many applications. Clifford Fourier transforms (CFT) allow holistic signal processing of (multi) vector fields, different from marginal (channel wise) processing: Flow fields, color fields, electromagnetic
fields, ... The Clifford algebra sets (manifolds) of $\sqrt{-1}$ lead to continuous manifolds of CFTs. A frequently asked

We consider also Schur-type theorems,
using the sliding hump technique, and prove some
convergence theorems in the particular case of
positive measures. We deal with
the notion of uniform filter exhaustiveness,
by means of which we prove some theorems
on existence of the limit measure,
some other kinds of limit theorems and their
equivalence, using known results on existence of
countably additive restrictions of strongly
bounded measures.

We investigate the order of
approximation of a real-valued function
by means of suitable families of sampling type
operators, which include both discrete
and integral ones. We give a unified approach, by
means of which it is possible to consider several
kinds of classical operators, for instance Urysohn
integral operators, in particular Mellin-type
convolution integrals, and generalized sampling
series. We deal with filter convergence, and our results are proper extensions of the classical ones.

The author has noted that matter begins with the natural logarithm e in a previous paper. The similarities and the high level mathematics lead towards the Clifford Algebra Cl (8) and the Exceptional Lie Algebra E8, which imply that Meso - American civilization enjoyed high - level mathematics.

First, the basic concept multivector functions and their vector derivative
in geometric algebra (GA) is introduced. Second, beginning
with the Fourier transform on a scalar function we generalize to a
real Fourier transform on GA multivector-valued functions (f : R^3 -> Cl(3,0)). Third, we show a set of important properties of the Clifford
Fourier transform (CFT) on Cl(3,0) such as dierentiation properties,
and the Plancherel theorem. We round o the treatment of the CFT
(at the end of this tutorial) by applying the Clifford Fourier transform
properties for proving an uncertainty principle for Cl(3,0) multivector
functions.
For wavelets in GA it is shown how continuous Clifford Cl(3,0)-
valued admissible wavelets can be constructed using the similitude
group SIM(3), a subgroup of the ane group of R^3. We express the
admissibility condition in terms of the CFT and then derive a set of
important properties such as dilation, translation and rotation covariance,
a reproducing kernel, and show how to invert the Clifford wavelet
transform of multivector functions. We explain (at the end of this tutorial)
a generalized Clifford wavelet uncertainty principle. For scalar
admissibility constant it sets bounds of accuracy in multivector wavelet
signal and image processing. As concrete example we introduce
multivector Clifford Gabor wavelets, and describe important properties
such as the Clifford Gabor transform isometry, a reconstruction
formula, and (at the end of this tutorial) an uncertainty principle for
Clifford Gabor wavelets.

We use the recent comprehensive research [17, 19] on the manifolds of
square roots of -1 in real Clifford’s geometric algebras Cl(p,q) in order to
construct the Clifford Fourier transform. Basically in the kernel of the complex
Fourier transform the imaginary unit j in C (complex numbers) is replaced by a square root
of -1 in Cl(p,q). The Clifford Fourier transform (CFT) thus obtained generalizes
previously known and applied CFTs [9, 13, 14], which replaced j in C
only by blades (usually pseudoscalars) squaring to -1. A major advantage
of real Clifford algebra CFTs is their completely real geometric interpretation.
We study (left and right) linearity of the CFT for constant multivector
coefficients in Cl(p,q), translation (x-shift) and modulation (w-shift) properties,
and signal dilations. We show an inversion theorem. We establish the
CFT of vector differentials, partial derivatives, vector derivatives and spatial
moments of the signal. We also derive Plancherel and Parseval identities as
well as a general convolution theorem.

We begin with introducing the generalization of real, complex, and quaternion numbers to hypercomplex
numbers, also known as Clifford numbers, or multivectors of geometric algebra. Multivectors encode everything from
vectors, rotations, scaling transformations, improper transformations (reflections, inversions), geometric objects (like
lines and spheres), spinors, and tensors, and the like. Multivector calculus allows to define functions mapping
multivectors to multivectors, differentiation, integration, function norms, multivector Fourier transformations and
wavelet transformations, filtering, windowing, etc. We give a basic introduction into this general mathematical
language, which has fascinating applications in physics, engineering, and computer science.

This paper treats the fundamentals of the vector differential calculus part of universal
geometric calculus. Geometric calculus simplifies and unifies the structure and notation of
mathematics for all of science and engineering, and for technological applications. In order to
make the treatment self-contained, I first compile all important geometric algebra relationships,
which are necessary for vector differential calculus. Then differentiation by vectors is introduced
and a host of major vector differential and vector derivative relationships is proven explicitly in a
very elementary step by step approach. The paper is thus intended to serve as reference material,
giving details, which are usually skipped in more advanced discussions of the subject matter.

In this paper, we generalize the classical windowed Fourier transform
(WFT) to quaternion-valued signals, called the quaternionic windowed
Fourier transform (QWFT).
Using the spectral
representation of the quaternionic Fourier transform (QFT), we derive
several important properties such as reconstruction formula,
reproducing kernel, isometry,
and orthogonality relation.
Taking the Gaussian function as window function we obtain quaternionic
Gabor filters which
play the role of coefficient functions when decomposing the signal in the
quaternionic Gabor
basis. We apply the QWFT properties and the (right-sided) QFT to establish
a Heisenberg type
uncertainty principle for the QWFT. Finally, we briefly introduce an
application of the QWFT to a linear time-varying system.

Recently several generalizations to higher dimension of the classical
Fourier transform (FT) using Clifford geometric algebra have been introduced, including
the two-dimensional (2D) Clifford Fourier transform (CFT). Based on the
2D CFT, we establish the two-dimensional Clifford windowed Fourier transform
(CWFT). Using the spectral representation of the CFT, we derive several important
properties such as shift, modulation, a reproducing kernel, isometry and an orthogonality
relation. Finally, we discuss examples of the CWFT and compare the CFT
and the CWFT.

We review the quaternionic Fourier transform (QFT). Using the properties of the QFT we establish an uncertainty principle for the right-sided QFT. This uncertainty principle prescribes a lower bound on the product of the effective widths of quaternion-valued signals in the spatial and frequency domains. It is shown that only a Gaussian quaternion signal minimizes the uncertainty.

**Comments:** 17 Pages. 2 Figures. Two theorems of rational structure are proved,

Rational structure in two dimension means that not only there exists an orthogonal net of curves in the plane but also, for each curve, the stellar density on one side of the curve is in constant ratio to the density on the other side of the curve. Such a curve is called a proportion curve or a Darwin curve. Such a distribution of matter is called a rational structure. Spiral galaxies are blended with dust and gas. Their longer wavelength (e.g. infrared) images present mainly the stellar distribution, which is called the naked galaxies. Jin He found many evidences that galaxies are rational stellar distribution. We list a few examples. Firstly, galaxy components (disks and bars) can be fitted with rational structure. Secondly, spiral arms can be fitted with Darwin curves. Thirdly, rational structure dictates New Universal Gravity which explains constant rotation curves simply and elegantly. This article presents the systematic theory of rational structure, its general solution and geometric meaning. A preliminary application to spiral galaxies is also discussed.

We have not found the general solution to the Creator's equation system. However, we have outlined the strategy for determining the solution. Firstly, we should study the stretch equation which is the first order linear and homogeneous partial differential equation, and find its all stretches which correspond to the given vector field (i.e., the gradient of the logarithmic stellar density). Our solution G(x,y), however, must be simultaneously the modulus of some analytic complex function. It is called the modulus stretch. Secondly, among all possible modulus stretches, we find the right solution (i.e., the orthogonal net of curves) which satisfies the Creator's standard equation.

This paper presents the local radial basis function based on finite difference (LRBF-FD) for the sine-Gordon equation. Advantages of the proposed method are that this method is mesh free unlike finite difference (FD) and finite element (FE) methods, and its coefficient matrix is sparse and well-conditioned as compared with the global RBF collocation method (GRBF). Numerical results show that the LRBF-FD method has good accuracy as compared with GRBF.

Let $ P(z) $ be a polynomial of degree $ n $ having all zeros in $|z|\leq k$ where $k\leq 1,$ then it was proved by Dewan \textit{et al} \cite{d} that for every real or complex number $\alpha$ with $|\alpha|\geq k$ and each $r\geq 0$
$$ n(|\alpha|-k)\left\{\int\limits_{0}^{2\pi}\left|P\left(e^{i\theta}\right)\right|^r d\theta\right\}^{\frac{1}{r}}\leq\left\{ \int\limits_{0}^{2\pi}\left|1+ke^{i\theta}\right|^r d\theta\right\}^{\frac{1}{r}}\underset{|z|=1}{Max}|D_\alpha P(z)|. $$
\indent In this paper, we shall present a refinement and generalization of above result and also extend it to the class of polynomials $P(z)=a_nz^n+\sum_{\nu=\mu}^{n}a_{n-\nu}z^{n-\nu},$ $1\leq\mu\leq n,$ having all its zeros in $|z|\leq k$ where $k\leq 1$ and thereby obtain certain generalizations of above and many other known results.

We prove the regularity of weak solutions of the navier-stokes equations for compressible,isentropic flow in three space dimension.We also prove the existence of a spatially periodic weak solution to the steady compressible navier-stokes equations for any specific heat ratio. Next we study the hyperbolic system of euler equations for isentropic,compressible fluid governed by a general law. We establish the vanishing viscosity limit of the navier-stokes equations to euler equations for one-dimensional compressible fluid flow.

Abstract: Recently the unified method for finding traveling wave solutions of non-linear evolution equations
was proposed by one of the authors a. It was shown that, this method unifies all the methods being used to find
these solutions. In this paper, we extend this method to find a class of formal exact solutions to Korteweg-de
Vries (KdV) equation with space dependent coefficients. A new class of multiple-soliton or wave trains is
obtained.

For many years lied a problem called the P vs NP. The question is to find the number of factorial possibilities to its orders. An example of this is finding the possibilities and comparison of improbabilities of picking 100 students out of 400 students. According to Lardner's theorem the number of known atoms in the universe is less then the number of combinations of possible orders and combinations of the answer to the P vs. NP problems. Finding the equation for the number of different orders a group of 400 people can be put into and subtracting 300 different people that couldn't get picked is equal to ((400!)-(100!*3)). My project is to represent this data through algorithms and different diagrams. When looking at my project you will know how I found a solution and the importance of it. My project will include all the required schematics, and graphs that coordinates with this answer. It will also acquire data showing different possibilities between P vs NP. As well as the combination where P can equal NP and N equals 1, or the possibilities where P doesn't equal NP and N isn't 1. P and NP is believed to stand for the number of possibilities and impossibilities.

The motion of fluids which are incompressible could be described by the Navier-Stokes differential equations. However, the three-dimensional Navier-Stokes equations for modelling turbulence misbehave very badly although they are relatively simple-looking. The solutions could wind up being extremely unstable even with nice, smooth, reasonably harmless initial conditions. A mathematical understanding of the outrageous behaviour of these equations would greatly affect the field of fluid mechanics. In this paper, which had been published in an international journal in 2010, a reasoned, practical approach towards resolving the issue is adopted and a practical, statistical kind of mathematical solution is proposed.

This paper discuss the longstanding problems of fractional calculus such as too
many definitions while lacking physical or geometrical meanings, and try to extend fractional
calculus to any dimension. First, some different definitions of fractional derivatives, such as the
Riemann-Liouville derivative, the Caputo derivative, Kolwankar's local derivative and Jumarie's modified
Riemann-Liouville derivative, are discussed and conclude that the very reason for introducing
fractional derivative is to study nondifferentiable functions. Then, a concise and essentially local
definition of fractional derivative for one dimension function is introduced and its geometrical
interpretation is given. Based on this simple definition, the fractional calculus is extended to
any dimension and the \emph{Fractional Geometric Calculus} is proposed. Geometric algebra provided
an powerful mathematical framework in which the most advanced concepts modern physic, such
as quantum mechanics, relativity, electromagnetism, etc., can be expressed in this framework
graciously. At the other hand, recent developments in nonlinear science and complex system
suggest that scaling, fractal structures, and nondifferentiable functions occur much more
naturally and abundantly in formulations of physical theories. In this paper, the extended
framework namely the Fractional Geometric Calculus is proposed naturally, which aims
to give a unifying language for mathematics, physics and science of complexity of the 21st century.

In this paper we have introduced a new topology and a convergence in Banach space, which would be called a L-topology and a L-convergence. It is similar to the weak topology and weak convergence, but there are some essential differences. For example, the L-topology is stronger than weak topology, but weaker than the strong one. On the basis of the notion, we have considered the problem on the separability and reflexibility of Lipschitz (Lip-) dual space. Furthermore, we have introduced a new topology of Lip-dual space, which is similar to the weak* (W*-) topology of linear dual of Banach space and would be called an L*-topology, and we have considered the problems on the metrizability of L*-topology and on the L*-separability of Lip-dual space, too.

In this paper we have introduced a new concept on the convergence of a sequence of the nonlinear Lipschitz (Lip-) functionals, which would be called an L*-convergence, and we have considered its applications in Banach spaces. This convergence is very similar to the weak* (W*-) convergence of the sequence of the bounded linear functionals, but there are some differences. By the L*-convergence, we have considered the problem on the relations of the compactness between the Lip-operator and its Lip-dual operator, and we have obtained the mean ergodic theorems for the Lip-operator.

In this paper we have obtained a new theorem that a nonlinear Lipschitz (Lip-) functional defined on the closed subset of Banach spaces can be extended to the whole space with Lip-continuity and maintenance of Lip-constant, which would be called an extension theorem (ET). This theorem is a generalization to the Lip-functional of the famous Hahn-Banach theorem on the bounded linear functional. By the ET, we have completely solved the open problem on the relation of the invertibility between the Lip-operator and its Lip-dual operator.

It is shown how the infinity of differential algebras of generalized
functions is naturally subjected to a basic dichotomic singularity test
regarding their significantly different abilities to deal with large classes
of singularities. In this respect, a review is presented of the way
singularities are dealt with in four of the infinitely many types of
differential algebras of generalized functions. These four algebras, in the
order they were introduced in the literature are : the nowhere dense,
Colombeau, space-time foam, and local ones. And so far, the first
three of them turned out to be the ones most frequently used in a
variety of applications. The issue of singularities is naturally not a
simple one. Consequently, there are different points of view, as well as
occasional misunderstandings. In order to set aside, and preferably,
avoid such misunderstandings, two fundamentally important issues
related to singularities are pursued. Namely, 1) how large are the sets
of singularity points of various generalized functions, and 2) how are
such generalized functions allowed to behave in the neighbourhood of
their point of singularity. Following such a two fold clarification on
singularities, it is further pointed out that, once one represents
generalized functions - thus as well a large class of usual singular functions
- as elements of suitable differential algebras of generalized functions,
one of the main advantages is the resulting freedom to perform
globally arbitrary algebraic and differential operations on such functions,
simply as if they did not have any singularities at all. With the same
freedom from singularities, one can perform globally operations such
as limits, series, and so on, which involve infinitely many generalized
functions. The property of a space of generalized functions of being
a flabby sheaf proves to be essential in being able to deal with large
classes of singularities. The first and third type of the mentioned
differential algebras of generalized functions are flabby sheaves, while the
second type fails to be so. The fourth type has not yet been studied
in this regard.

This article presents two methods, in parallel, of solving more complex integrals, among
which is the Poisson's integral, in order to emphasize the obvious advantages of a new method
of integration, which uses the supermathematics circular ex-centric functions.
We will specially analyze the possibilities of easy passing/changing of the supermathematics
circular ex-centric functions of a centric variable α to the same functions of ex-centric variable &theta.
The angle α is the angle at the center point O(0,0), which represents the centric variable and θ
is the angle at the ex-center E(k,ε), representing the ex-centric variable. These are the angles
from which the points W_{1} and W_{2} are visible on the unity circle - resulted from the intersection
of the unity/trigonometric circle with the revolving straight line d around the ex-centric
E(k,&epsilon) - from O and from E, respectively.

certain set of orthogonal Polynomials, we study the 'Hamburger moment problem' for even 'n' and 0 for n
odd here the moments are related to the power series expansion of Xi-function , we also give the
integral representation for the generating function , in terms of the Laplace transform of , and
in the end of the paper we study the connection of our orthogonal polynomial set with the Kernel ,
through all the paper we will use the simplified notation (see paper for abstract with equations)

I deduce a series which satisfies the fundamental theorem of calculus without dependence on an
explicit function. I prove Taylor's theorem and show that it is closely related. I deduce a series for the
logarithm function and from this series deduce the power series representation of the logarithm function
along with the interval of convergence. I also solve an ordinary differential equation.

In this work I am going to mention historical development of divergent series theory, and to give a number of different examples, as some of the methods for their summing. After that, I am going to introduce the general method, which I discovered, for summing divergent series, which we can also consider as a method for computing limits of divergent sequences and functions in divergent points, In this case, limits of sequences of their partials sums. Through the exercises, I am going to apply this method on given examples and prove its validity. Then I'm going to apply the method to compute the value of some divergent integrals.

The reference [2] contructs the Operator axioms to deduce number systems. In this paper, we slightly improve on the syntax of the Operator axioms and construct a semantics of the Operator axioms. Then on the basis of the improved Operator axioms, we define two fundamental operator functions to study the analytic properties of the Operator axioms. Finally, we prove two theorems about the fundamental operator functions.

An elementary algebra of products of distributions is constructed. The constructed algebra is equivalent, although less general, of the full Colombeau algebra of generalised functions. However, the loss of generality is compensated by the fact that the new algebra of generalised functions is very convenient for practical calculations. An equivalent relation, among elements of the above algebra, is proposed and a linear space of generalised functions is constructed as a partition space of the elementary algebra with respect to the equivalent relation. The new space of generalized functions is used to prove interesting equalities involving products among elements of D'. A way of multiplying the defined generalised functions with polynomials is also given.

The motion of fluids which are incompressible could be described by the Navier-Stokes differential equations. However, the
three-dimensional Navier-Stokes equations for modelling turbulence misbehave very badly although they are relatively simplelooking. The solutions could wind up being extremely unstable even with nice, smooth, reasonably harmless initial conditions. A mathematical understanding of the outrageous behaviour of these equations would greatly affect the field of fluid mechanics.
In this paper, which had been published in the International Journal of Nonlinear Science, Vol. 10 (2010) No. 3, pp.264-278, a reasoned, practical approach towards resolving the issue is adopted and a practical, statistical kind of mathematical solution is proposed.

In this paper we have introduced a new concept on the convergence of a sequence of the nonlinear Lipschitz (Lip-) functionals, which would be called an L*-convergence, and we have considered its applications in Banach spaces. This convergence is very similar to the weak* (W*-) convergence of the sequence of the bounded linear functionals, but there are some differences. By the L*-convergence, we have considered the problem on the relations of the compactness between the Lip-operator and its Lip-dual operator, and we have obtained the mean ergodic theorems for the Lip-operator.

It is shown how the infinity of differential algebras of generalized
functions is naturally subjected to a basic dichotomic singularity test
regarding their significantly different abilities to deal with large classes
of singularities. In this respect, a review is presented of the way
singularities are dealt with in four of the infinitely many types of
differential algebras of generalized functions. These four algebras, in the
order they were introduced in the literature are : the nowhere dense,
Colombeau, space-time foam, and local ones. And so far, the first
three of them turned out to be the ones most frequently used in a
variety of applications. The issue of singularities is naturally not a
simple one. Consequently, there are different points of view, as well as
occasional misunderstandings. In order to set aside, and preferably,
avoid such misunderstandings, two fundamentally important issues
related to singularities are pursued. Namely, 1) how large are the sets
of singularity points of various generalized functions, and 2) how are
such generalized functions allowed to behave in the neighbourhood of
their point of singularity. Following such a two fold clarification on
singularities, it is further pointed out that, once one represents
generalized functions - thus as well a large class of usual singular functions
- as elements of suitable differential algebras of generalized functions,
one of the main advantages is the resulting freedom to perform
globally arbitrary algebraic and differential operations on such functions,
simply as if they did not have any singularities at all. With the same
freedom from singularities, one can perform globally operations such
as limits, series, and so on, which involve infinitely many generalized
functions. The property of a space of generalized functions of being
a flabby sheaf proves to be essential in being able to deal with large
classes of singularities. The first and third type of the mentioned
differential algebras of generalized functions are flabby sheaves, while the
second type fails to be so. The fourth type has not yet been studied
in this regard.

Using the theory of distributions and Zeta regularization we manage to give
a definition of product for Dirac delta distributions, we show how the fact of one can be
define a coherent and finite product of Dirac delta distributions is related to the
regularization of divergent integrals ... (see paper for full abstract)

A great number of articles widen known scientific results (theorems, inequalities,
math/physics/chemical etc. propositions, formulas), and this is due to a simple procedure,
of which it is good to say a few words:
Let suppose that we want to generalizes a known mathematical proposition P(a) ,
where a is a constant, to the proposition P(n) , where n is a variable which belongs to
subset of N .
To prove that P is true for n by recurrence means the following: the first step is
trivial, since it is about the known result P(a) (and thus it was already verified before by
other mathematicians!). To pass from P(n) to P(n + 1) , one uses too P(a) : therefore one
widens a proposition by using the proposition itself, in other words the found
generalization will be paradoxically proved with the help of the particular case from
which one started!
We present below the generalizations of Hölder, Minkovski, and respectively
Tchebychev inequalities.
