It is proved that it gives essentially a first-order parameter-uniform convergence in the discrete maximum norm. Furthermore, numerical results are presented in support of the theory.eninfo:eu-repo/semantics/closedAccessSingular PerturbationBoundary-Value ProblemDelay Differential EquationUniform ConvergenceShishkin MeshArticle163Q2Q2WOS:000464743800002
