The finite difference scheme is established on Boglaev- Bakhvalov type mesh. The error approximations are obtained in the discrete maximum norm. A numerical example is solved to clarify the theoretical analysis.eninfo:eu-repo/semantics/openAccessMatematikFizikMatematikNumerical Solutions of the Singularly Perturbed Semilinear Delay Differential EquationsArticle272N/AN/A3303431144018
