| Abstract: | In this paper, a uniform numerical solution of the elliptic equation singular perturbation problem with two directions of turning points is considered. The uniformly convergent results of difference scheme with the exponential fitted factors are proved. In the end of paper, a numerical example is given, which shows the correctness of the theoretical results. |
