An Efficient Computational Technique for Nonlinear Emden-Fowler Equations Arising in Astrophysics and Space Science

摘要

In the present article, we suggest an efficient computational scheme to examine nonlinear Emden-Fowler equations arising in astrophysics and space science. The suggested scheme is based on a modified theory of the Adomian polynomials, and the two steps Adomian decomposition technique mixed with the padé approximant. Moreover, a maple software package ADMP is used to apply the suggested computational scheme, which is very simple to perform and well organized. The input of the system requires initial or boundary conditions and many desired parameters to find the analytic approximate solutions within a very short time. The following algorithm does not require linearization, perturbations, guessing the initial terms and any restrictive supposition, which may leads the solutions in closed form. Several examples are discussed to illustrate the reliability of the algorithm.
