Application of He’s Homotopy Perturbation Method to Stiff Systems of Ordinary Differential Equations

In this paper, the approximate analytical solutions of a general diffusion equation with fractional time derivative in the presence of a linear external force are obtained with the

The new application accelerates the rapid convergence of the series solutions and is used for analytic treatment of these equations.. Some illustrative examples are given to

The traditional perturbation methods are based on assuming a small parameter, and the approximate solutions obtained by those methods, in most cases, are valid only for small values

In this paper, we present an efficient modification of the homotopy perturbation method by using Chebyshev’s polynomials and He’s polynomials to solve some nonlinear

In this work, we successfully apply He’s homotopy perturbation method in combination with Chebyshev’s polynomials to solve the differential equations with source term for which

The results show that the method provides a straightforward and powerful mathematical tool for solving various nonlinear integro-differential equations. Key words: He’s

The discretized modified Korteweg- de Vries (mKdV) lattice equation and the discretized nonlinear Schr¨odinger equation are taken as examples to illustrate the validity and the
