First, the boundary layer behavior of the exact solution and its first derivative have been estimated. Then we construct a finite difference scheme on a uniform mesh. We prove the uniform convergence of the proposed difference scheme and give an error estimate. We also present numerical examples, which demonstrate computational efficiency of the proposed method.eninfo:eu-repo/semantics/closedAccessSingular PerturbationBoundary Value ProblemExponentially Fitted Difference SchemeUniformly ConvergenceNonlocal ConditionArticle602Q4Q3147160WOS:000516035800002
