摘要：
We have constructed a robust numerical method on Shishkin mesh for a class of convection diffusion type turning point problems with Robin type boundary conditions. Supremum norm is used to derive error estimates which is of order O(N-1 In N). Theoretical results are verified by providing numerical examples.
