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

open access: yesMathematics 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.

On helicity and spin on the light cone [PDF]

open access: yes, 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.

Integral equation mei applied to three-dimensional arbitrary surfaces [PDF]

open access: yes, 1997
The authors present a new formulation of the integral equation of the measured equation of invariance (MEI) as a confined field integral equation discretised by the method of moments, in which the use of numerically derived testing functions results in ...

Chandrasekhar quadratic and cubic integral equations via Volterra-Stieltjes quadratic integral equation

open access: yesDemonstratio Mathematica, 2021
In this work, we study the existence of one and exactly one solution x∈C[0,1]x\in C\left[0,1], for a delay quadratic integral equation of Volterra-Stieltjes type.

Analysis of Two-Dimensional Heat Transfer Problem Using the Boundary Integral Equation

open access: yesAdvances in Mathematical Physics, 2022
In this paper, we examine the problem of two-dimensional heat equations with certain initial and boundary conditions being considered. In a two-dimensional heat transport problem, the boundary integral equation technique was applied.

Mesh-based numerical implementation of the localized boundary-domain integral equation method to a variable-coefficient Neumann problem [PDF]

open access: yes, 2005
An implementation of the localized boundary-domain integral-equation (LBDIE) method for the numerical solution of the Neumann boundary-value problem for a second-order linear elliptic PDE with variable coefficient is discussed.
