Initially, some properties are given for the continuous problem. Then, using interpolating quadrature formulas [3], the finite difference scheme is established on the Bakhvalov-Shishkin mesh (B-S mesh). The error approximations of the suggested scheme are examined in the discrete maximum norm. Finally, some numerical examples are included to confirm the theory.eninfo:eu-repo/semantics/closedAccessBakhvalov-Shishkin MeshError AnalysisFinite Difference SchemeSingular PerturbationArticle1783N/AQ4381391WOS:001378412000005
