Retraction:The rational third-kind chebyshev pseudospectral method for the solution of the thomas-fermi equation over infinite interval

Abstract

We propose a pseudospectral method for solving the Thomas-Fermi equation which is a nonlinear ordinary differential equation on semi-infinite interval. This approach is based on the rational third-kind Chebyshev pseudospectral method that is indeed a combination of Tau and collocation methods. This method reduces the solution of this problem to the solution of a system of algebraic equations. Comparison with some numerical solutions shows that the present solution is highly accurate. © 2013 Majid Tavassoli Kajani et al.
