An almost second order uniformly convergent method for a two-parameter singularly perturbed problem with a discontinuous convection coefficient and source term

AIMS Mathematics
In this paper, we discuss a higher-order convergent numerical method for a two-parameter singularly perturbed differential equation with a discontinuous convection coefficient and a discontinuous source term.

Some comparisons of difference schemes on meshes of Shishkin and Bakhvalov type

Novi Sad Journal of Mathematics - NSJOM, 2001
The authors consider the spline finite difference schemes approximating a linear selfadjoint singularly perturbed boundary value problem on the meshes of Bakhvalov and Shishkin types. A finite difference scheme, that produces better results on the Shishkin mesh than on the Bakhvalov type mesh, is presented. Numerical examples are obtained.
