Abstract:
A singularly perturbed convection diffusion equation with boundary turning point is considered in this paper. A higher order method on piecewise uniform Shishkin mesh is suggested to solve this problem. We prove that this method is of order O(N^{-۲}(\ln N)^۲). Numerical results are given which validate the analytical results.
