Division by Zero Calculus and Singular Integrals

Authors: Saburou Saitoh
Comments: 10 Pages. In this paper, we will show a very interesting interpretation of singular integrals by the division by zero calculus. This may be considered as the basic relation of ZERO and INFINITY through integrals. Furthermore, we will see a similar nature of singula

What are the singular integrals? Singular integral equations are presently encountered in a wide range of mathematical models, for instance in acoustics, fluid dynamics, elasticity and fracture mechanics. Together with these models, a variety of methods and applications for these integral equations has been developed. In this paper, we will give the interpretation for the Hadamard finite part of singular integrals by means of the division by zero calculus.

Integration Technique Using Laplace Transforms. a Generalized Form of the Dirichlet Integral.

Authors: Federico Espil
Comments: 9 Pages.

The problem of integration technique over integrands of the form f(t)/t^n, can be solved by differentiation(n times) by using Leibniz's rule to get rid of t^n, that leads to integrate back (n times) to end the game which it's harder than the original problem.This work focuses on the derivation of the formula (Espil's theorem) which is a perfect tool to avoid that hard task. It allows to change the difficult n iterated integrals into a more outstanding easier problem which consists of n -1 derivatives.The Espil's theorem is a generalization of the Dirichlet integral.

Soft and Hard Liberation of Compact Lie Groups

Authors: Teo Banica
Comments: 12 Pages.

We investigate the liberation question for the compact Lie groups, by using various ``soft'' and ``hard'' methods, based respectively on joint generation with a free quantum group, and joint generation with a free torus. The soft methods extend the ``easy'' methods, notably by covering groups like $SO_N,SU_N$, and the hard methods partly extend the soft methods, notably by covering the real and complex tori themselves.

Division by Zero Calculus in Multiply Dimensions and Open Problems

Authors: Saburou Saitoh
Comments: 9 Pages. In this paper, we will introduce the division by zero calculus in multiply dimensions in order to show some wide and new open problems as we see from the one dimensional case.

Espil's High Power Partial Fraction Decomposition Theorem.

Authors: Federico Espil
Comments: 6 Pages.

The problem of fraction decomposition it's easy to solve by using the cover up method, when there are no repeated linear factors in the denominator . Nevertheless it could turn into a hard work if these factors are raised to a high power, where the cover up method doesn't work. This technique shows how to calculate these coefficients without solving large systems of equations with a clever rearrangement of the numerator.

Differential Equation

Authors: Fayowole David Ayadi
Comments: 3 Pages.

The laws of Physics and some other related courses are generally written as differential equations. Therefore, all of science and engineering use differential equations to some extent. A good knowledge of differential equations will be an integral part of your study in science and/or engineering classes. You can think of mathematics as the language of science, and differential equations are one of the most important parts of this language as far as science and engineering are concerned.

Espil's Theorem Corollary.

Authors: Federico Espil
Comments: 5 Pages.

Shortly from the Espil's theorem, we can derive the generalized Dirichlet integral for any natural value when the hole integrand is raised to the n-th power.
