报告摘要：IMEX-LDG method is a kind of fully discrete method adopting implicit-explicit (IMEX) time discretization coupled with local discontinuous Galerkin (LDG) spatial discretization methods. One can benefit from the IMEX temporal discretization because it can ensure a good balance of the computational efficiency and numerical stability for time-dependent problems with both stiff and nonstiff parts. In this talk, I will first introduce a new approach using forward temporal differences and backward temporal differences to obtain uniform stability of IMEX-LDG methods for convection-diffusion equations. Then I will briefly introduce some related work, including boundary treatment, applications of IMEX-LDG methods in incompressible fluid flow, and some extensions to IMEX-DDG and IMEX-UWDG methods.
