In this context, firstly, priori estimates are given and a new discretization is constructed on piecewise-equidistant mesh by using interpolating quadrature rules [2] and composite integration formulas. Then, the convergence analysis and stability bounds of the presented method are discussed. Finally, numerical results are demonstrated with two test problems.eninfo:eu-repo/semantics/closedAccessDelay Differential EquationDifference SchemeIntegro-Differential EquationSingular PerturbationUniform ConvergenceArticle479Q3Q219131933WOS:001216117100001
