In this study, homotopy perturbation method (HPM) is used to obtain analytic and approximate solutions of the space- time-fractional telegraph equations. The derivatives are considered in Caputo sense. calculated form a series with easily computable terms. Some examples given. results reveal that HPM very effective convenient.

In this paper, we propose a powerful modification of the homotopy perturbation method that will accelerate rapid convergence series solution. The modified is employed to solve MHD boundary-layer equations. viscous fluid electrically conducting in presence uniform applied magnetic field and induced neglected for small Reynolds number. Similarity solutions ordinary differential equation resulting from momentum are obtained. Finally, some numerical comparisons among new method, standard...
