Abstract:Numerical solution of a singularly perturbed problem for the semilinear parabolic differential equation with parabolic boundary layers is discussed, A nonlinear two-level difference scheme is constructed on the special non-uniform grids. The uniform convergence of this scheme is proved and some numerical examples are given.
Keywords:semilinear parabolic differential equation  singularly perturbed problem  finite difference method  uniform convergence
