The objective of this paper is to present a comparative study of fitted-mesh finite difference method, Ritz-Galerkin finite element method and B-spline collocation method for a two-parameter singularly perturbed boundary value problems. Due to the small parameters ϵ and µ, the boundary layers arise. We have taken a piecewise-uniform fitted-mesh to resolve(More)

It is based on the usual(More)
