【Abstract】 In this paper, we consider the upwind difference scheme for singular perturbation problem (1.1). On a special discretization mesh, it is proved that the solution of upwind difference scheme is first order convergent, uniformly in the small parameter e, to the solution of problem (1.1). Numerical results are finally provided.更多还原
