Non-Standard Finite Difference Schemes for Solving Singular Lane-Emden Equation

H. Saberi Najafi; A. Yaghoubi

Volume 6, Issue 2 , June 2017, Pages 161-171

  In this paper we construct Non-Standard finite difference schemes (NSFD) for numerical solution of nonlinear Lane-Emden type equations which are nonlinear ordinary dierential equations on semi-infinite domain. They are categorized as singular initial value problems. This equation describes a variety ...  Read More
