ملخص المقالة :
In this paper, we utilize an algorithm for solving nonlinear ordinary differential equations of Lane-Emden type on a semi-infinite interval. The algorithm is based on an iterative technique and thereproducing kernel Hibert method. We give the convergence analysis for the proposed method. The validity and applicability of the proposed method are demonstrated by some numerical examples. The obtained results and comparison with other methods provide confirmation for the validity of our numerical method.
