New application of He's homotopy perturbation method

Homotopy perturbation method (HPM) is used for solving coupled Schrodinger-KdV and shallow water equations. In contrast to classical perturbation techniques, the homotopy perturbation method does not require small or large parameters, thus this method can be used to obtain formulae uniformly valid for both small and large parameters in non-linear problems. The results reveal that the present method is very effective and convenient. It is predicted that the method can be found widely applications in science and engineering.
