APPROXIMATE SOLUTION OF ZAKHAROV-KUZNETSOV EQUATION VIA HOMOTOPY PERTURBATION METHOD.

In this paper, Homotopy Perturbation Method (HPM) is applied to find the approximate solutions of ZK equations. It is proved that the HPM gives a powerful tool for solving a large number of nonlinear partial differential equations in mathematical physics. The solutions obtained by HPM are presented graphically. [ABSTRACT FROM AUTHOR]
