Comparison between the variational iteration method and the homotopy perturbation method for the sturm-liouville differential equation

Abstract

We applied the variational iteration method and the homotopy perturbation method to solve Sturm-Liouville eigenvalue and boundary value problems. The main advantage of these methods is the flexibility to give approximate and exact solutions to both linear and nonlinear problems without linearization or discretization. The results show that both methods are simple and effective. Copyright © 2010 A. Neamaty and R. Darzi.
