A New Integral Transform for Solving Integral and Ordinary Differential Equations [PDF]

Mathematics and Computational Sciences
In this research paper, we introduce a new transform belonging to the class of Laplace transforms, called the Yasser-Jassim Transform (YJ Transform). We explore its properties and compare it to the classical Laplace transform.

An approximation method for the solution of nonlinear integral equations [PDF]

, 2006
A Chebyshev collocation method has been presented to solve nonlinear integral equations in terms of Chebyshev polynomials. This method transforms the integral equation to a matrix equation which corresponds to a system of nonlinear algebraic equations ...

The effect of near-zone preconditioning on electromagnetic integral equations of first and second kind [PDF]

Advances in Radio Science, 2013
The linear equation systems which arise from the discretization of surface integral equations are conveniently solved with iterative methods because of the possibility to employ fast integral methods like the Multilevel Fast Multipole Method.

On helicity and spin on the light cone [PDF]

, 2001
Starting from a one-body front-form equation with Lepage-Brodsky spinors we show, with a fair amount of new technology, how an integral equation in standard momentum space with Bjorken-Drell spinors can be obtained.
