To solve the problem, we construct a new difference scheme by the method of integral identities using interpolating quadrature rules with remainder terms in integral form. We prove that the method is convergent in the discrete maximum norm, uniformly with respect to the perturbation parameter. We present numerical experiments which support the theoretical results.eninfo:eu-repo/semantics/closedAccessFredholm Integro-Differential EquationSingular PerturbationFinite Difference MethodUniform ConvergenceArticle
