Theory and computation in singular boundary value problems

This paper applies the Sinc-Galerkin method and He's homotopy perturbation method to search for approximate solutions of a certain class of singular two-point boundary value problems. The sinc method converges exponentially to the exact solution. A new iterative scheme based on He's homotopy perturbation method is proposed for the discussed problem. A numerical example is given to demonstrate the computational efficiency of the two methods.
