Uniformly convergent finite difference methods for singularly perturbed problems with turning points
A family of finite difference schemes including the upwind method, Samarskij's method and exponential fitting type methods are studied for finding the approximate solution of one-dimensional singular perturbation problems with turning points. Uniform convergence of the upwind method on irregular meshes is established. Many examples are given to illustrate the efficiency of the proposed methods.
