Superconvergence analysis of DG-FEM based on the polynomial preserving recovery for Helmholtz equation with high wave number
Yu Du, Zhimin Zhang
We study superconvergence property of the linear discontinuous Galerkin finite element method with the polynomial preserving recovery (PPR) and Richardson extrapolation for the two…
Analysis of -Galerkin FEMs for time-fractional nonlinear parabolic problems
Dongfang Li, Hong-lin Liao, Weiwei Sun +2
This paper is concerned with numerical solutions of time-fractional nonlinear parabolic problems by a class of -Galerkin finite element methods. The analysis of methods fo…
Uniform error bounds of a finite difference method for the Klein-Gordon-Zakharov system in the subsonic limit regime
