In this study, the implantation of a new semi-analytical method called optimal auxiliary function (OAFM) has been extended to partial differential equations. The adopted was tested upon for approximate solution generalized modified b-equation. first-order numerical obtained by OAFM compared with variational homotopy perturbation (VHPM). possesses and control parameters which can be easily handl...

In this paper, we apply the  homotopy analysis method (HAM) for solving fuzzy  linear systems and present  the necessary and sufficient conditions for the convergence of series solution obtained via the HAM. Also, we present a new criterion for choosing a proper value of convergence-control parameter $hbar$ when the HAM is applied to linear system of equations. Comparisons are made between the ...

We show that a recent application of homotopy perturbation method to a class of ordinary differential equations yields either useless or wrong results. There has recently been great interest in the application of several approximate procedures, like the homotopy perturbation method (HPM), the Adomian decomposition method (ADM), and the variation iteration method (VIM), to a variety of linear an...

A numerical solution for solving non-linear Fredholm integral equations is presented. The method is based upon homotopy perturbation theory. The result reveal that the modified homotopy perturbation method (MHPM) is very effective and convenient. 2007 Elsevier Ltd. All rights reserved.
