| 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. |
