A higher order method on piecewise uniform Shishkin mesh is suggested to solve this problem. We  prove that this method is of  order $O(N^{-2}(\ln N)^2)$. Numerical results are given which validate  the analytical results.}, keywords = {Singular perturbation,boundary turning point,hybrid difference scheme,Shishkin}, url = {https://jmm.guilan.ac.ir/article_4758.html}, eprint = {https://jmm.guilan.ac.ir/article_4758_8e7f2014d3bcedb899496b890f1c3f01.pdf} }
