Supercloseness of the NIPG method for a singularly perturbed convection diffusion problem on Shishkin mesh in 2D
Xiaoqi Ma, Jin Zhang
As a popular stabilization technique, the nonsymmetric interior penalty Galerkin (NIPG) method has significant application value in computational fluid dynamics. In this paper, we…

Supercloseness analysis of the nonsymmetric interior penalty Galerkin method on Bakhvalov-type mesh
Xiaoqi Ma, Jin Zhang
In this paper, we study the convergence of the nonsymmetric interior penalty Galerkin (NIPG) method on a Bakhvalov-type mesh for the first time. For this purpose, a new composite i…
