【Abstract】 In this paper, we consider the numerical solution for a class of singUlarly perturbed elliptic equation with turning points as follows The peper [1] has studied the aspoptotic solution of this problem. After obtaining a better result about estimation of the remainder, we prove the uniform convergence on the small parameter E for a difference scheme. The estimate error is of order or which is in (0, ).更多还原
