SOLVING HELMHOLTZ EQUATION BY THE HOMOTOPY PERTURBATION TRANSFORM METHOD R.RAJARAMAN & G.HARIHARAN Department of Mathematics, School of Humanities & Sciences, SASTRA University, Thanjavur,Tamilnadu, India ABSTRACT In this paper, Homotopy Perturbation transform Method (HPTM) is used for analytic treatment of the Helmholtz equation. This method is the combined form of Homotopy perturbation method and Laplace transform method. The Nonlinear terms can be easily decompo
