In this paper, a simple scheme is constructed for finding approximate solution of the nonlinear Fredholm integral equation second kind. To end, Lagrange interpolation polynomials together with Gauss-Legendre quadrature rule are used to transform source problem system algebraic equations. Afterwards, resulting can be solved by Newton method. The basic idea choose points same as integration. This...

A new and effective direct method to determine the numerical solution of specific nonlinear Volterra-Fredholm integral and integro-differential equations is proposed. The method is based on vector forms of block-pulse functions (BPFs). By using BPFs and its operational matrix of integration, an integral or integro-differential equation can be transformed to a nonlinear system of algebraic equat...

In this work, the modified Lyapunov-Schmidt reduction is used to find a nonlinear Ritz approximation of Fredholm functional defined by nonhomogeneous Camassa-Holm equation and Benjamin-Bona-Mahony. We introduced for problems when dimension null space equal two. The has been found as function codimension twenty-four.

A numerical algorithm, based on a decomposition technique, is presented for solving a class of nonlinear integral equations. The scheme is shown to be highly accurate, and only few terms are required to obtain accurate computable solutions. 1. Introduction. Adomian polynomial algorithm has been extensively used to solve linear and nonlinear problems arising in many interesting applications (see...

In this paper, a numerical procedure for solving a class of nonlinear VolterraFredholm integral equations is presented. The method is based upon the globally defined sinc basis functions. Properties of the sinc procedure are utilized to reduce the computation of the nonlinear integral equations to some algebraic equations. Illustrative examples are included to demonstrate the validity and appli...
