A new parameter-convergent nonstandard finite difference method for two-parameter singularly perturbed problems

Discover Applied Sciences
This article focuses on the numerical solution of a time-dependent parabolic problem that exhibits singular perturbations and involves two perturbation parameters. To address this problem, a fitted mesh finite difference method is developed. In numerical

Parameter uniform hybrid numerical method for time-dependent singularly perturbed parabolic differential equations with large delay

Applied Mathematics in Science and Engineering
In this study, to solve the singularly perturbed delay convection–diffusion–reaction problem, we proposed a hybrid numerical scheme that converges uniformly.
