Abstract

Purpose

In this paper, we shall investigate the numerical solution of two-dimensional Fredholm integral equations (2D-FIEs).

Methods

In this work, we apply two-dimensional Haar wavelets, to solve linear two dimensional Fredholm integral equations (2D-FIEs). Using 2D Haar wavelets and their properties, 2D-FIEs of the second kind reduce to a system of algebraic equations.

Results

The numerical examples illustrate the efficiency and accuracy of the method.

Conclusions

In comparison with other bases (for example, polynomial bases), one of the advantages of this method is, although the involved matrices have a large dimension, they contain a large percentage of zero entries, which keeps computational effort within reasonable limits.
