Abstract
A singularly perturbed reaction-diffusion problem with two small parameters is considered. Due to these two small parameters boundary layers exist. To resolve the boundary layers a piecewise-uniform Shishkin mesh has been taken and we have shown that the Ritz-Galerkin method has almost second order parameters-uniform convergence. Numerical experiments support these theoretical results.
