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.

Supercloseness of the DDG method for a singularly perturbed convection diffusion problem on Shishkin mesh

Applied Mathematics and Computation
This paper investigates the supercloseness of a singularly perturbed convection diffusion problem using the direct discontinuous Galerkin (DDG) method on a Shishkin mesh. The main technical difficulties lie in controlling the diffusion term inside the layer, the convection term outside the layer, and the inter element jump term caused by the ...
