Supercloseness of the HDG method on Shishkin mesh for a singularly perturbed convection diffusion problem in 2D
Xiaoqi Ma, Jin Zhang
This paper presents the first analysis of parameter-uniform convergence for a hybridizable discontinuous Galerkin (HDG) method applied to a singularly perturbed convection-diffusio…

Supercloseness of the DDG method for a singularly perturbed convection diffusion problem on Shishkin mesh
Xiaoqi Ma, Jin Zhang, Xinyi Feng +1
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…
