A modification for solving Fredholm‐Hammerstein integral equation by using wavelet basis

Abstract

Purpose

The purpose of this paper is to use Alpert wavelet basis and modify the integrand function approximation coefficients to solve Fredholm‐Hammerstein integral equations.

Design/methodology/approach

L²[0, 1] was considered as solution space and the solution was projected to the subspaces of L²[0, 1] with finite dimension so that basis elements of these subspaces were orthonormal.

Findings

In this process, solution of Fredholm‐Hammerstein integral equation is found by solving the generated system of nonlinear equations.

Originality/value

Comparing the method with others shows that this system has less computation. In fact, decreasing of computations result from the modification.
