A fitted mesh robust numerical method and analysis for the singularly perturbed parabolic PDEs with a degenerate coefficient

In this study, we present a nearly second-order central finite difference approach for solving a singularly perturbed parabolic problem with a degenerate coefficient. The approach uses a Crank–Nicolson method to discretize the time direction on the uniform mesh and a second-order central finite diff...
