A Robust computational method for singularly perturbed coupled system of reaction-diffusion boundary-value problems (Q2371442)

The authors devise a robust computational method for singularly perturbed systems of reaction-diffusion boundary-value problems on a piecewise uniform Shishkin mesh on the whole domain. They prove that this newly proposed scheme is uniformly stable throughout the domain and provides second-order uniform convergence results, and give a test problem to verify the efficiency and accuracy of the method.
