Finite difference method is used to discretize this problem on the Bakhvalov-Shishkin mesh. The some properties of exact solution are analyzed. The error is obtained first-order in the discrete maximum norm. Finally, an example is solved to show the advantages of the finite difference method. © MatDer.eninfo:eu-repo/semantics/openAccessBakhvalov-Shishkin MeshFinite Difference MethodIntegral ConditionsSingular Perturbation EquationUniform ConvergenceArticle142N/AN/A2352471148646
