Robust numerical methods for two-parameter singularly perturbed parabolic problems with non-smooth data

A uniformly convergent numerical scheme is developed to address two-parameter singularly perturbed parabolic equations involving discontinuous convection coefficients and source terms. These problems are challenging because the small perturbation parameters cause sharp boundary and interior layers,...
