Application of homotopy perturbation method to multidimensional partial differential equations.

In this paper, an application of homotopy perturbation method (HPM) is applied to solve the kindly of multidimensional partial differential equation such as Helmholtz equation. Comparisons are made between the Adomians decomposition method and HPM. The results reveal that the HPM is very effective and simple and gives the exact solution. [ABSTRACT FROM AUTHOR]
