چکیده

In this paper, variational homotopy perturbation method (VHPM) is used to obtain analytical solution for the time-dependent Emden-Fowler type of equations with singular behavior. The advantage of this work is twofold. Firstly, the VHPM reduces the computational work. Secondly, in comparison with existing techniques, the VHPM is an improvment with regard to its accuracy and rapid convergence. To show the efficiency of the VHPM, several examples are presented. Comparisons with exact solution show that the VHPM is a powerfull method for the solution of linear and nonlinear equations.

Solutions of time-dependent Emden–Fowler type equations by homotopy-perturbation method

In this Letter, we apply the homotopy-perturbation method (HPM) to obtain approximate analytical solutions of the time-dependent Emden– Fowler type equations. We also present a reliable new algorithm based on HPM to overcome the difficulty of the singular point at x = 0. The analysis is accompanied by some linear and nonlinear time-dependent singular initial value problems. The results prove th...

A New Approach to Homotopy Perturbation Method for Solving Emden–Fowler Equations

In this article, we presented a new approach deduced from He’s homotopy perturbation method (HPM) to obtain exact and/or approximate analytical solutions of Emden–Fowler type equations. The results reveal that the proposed algorithm is very effective and in most cases yield exact solutions in the first approximation. Some examples are given to illustrate the new approach.

THE APPLICATION OF THE VARIATIONAL HOMOTOPY PERTURBATION METHOD ON THE GENERALIZED FISHER'S EQUATION

In this paper, we consider the variational homotopy perturbation method (VHPM) to obtain an approximate series solution for the generalized Fisher’s equation which converges to the exact solution in the region of convergence.
