Abstract

In this study a numerical method is developed to solve the Hammerstein integral
equations. To this end the kernel has been approximated using the leastsquares
approximation schemes based on Legender-Bernstein basis. The Legender
polynomials are orthogonal and these properties improve the accuracy of the
approximations. Also the nonlinear unknown function has been approximated by
using the Bernstein basis. The useful properties of Bernstein polynomials help
us to transform Hammerstein integral equation to solve a system of nonlinear
algebraic equations.
