Homotopy perturbation method for coupled Schrodinger-KdV equation

In this paper, numerical analysis of the coupled Schrodinger-KdV equation is studied by using the Homotopy Perturbation Method (HPM). The available analytical solutions of the coupled Schrodinger-KdV equation obtained by multiple traveling wave method are compared with HPM to examine the accuracy of the method. The numerical results validate the convergence and accuracy of the Homotopy Perturbation Method for the analyzed coupled Schrodinger-KdV equation. (C) 2008 Elsevier Ltd. All rights reserved.
