摘要 :During the past three decades, many different discontinuous finite element methods (FEMs), including discontinuous Galerkin (DG) methods, hybrid DG methods and weak Galerkin methods, have been developed for solving a wide range of partial differential equations. In this talk, taking Poisson problem as an example we present a general framework for understanding these discontinuous finite element methods by the concept of DG-derivatives. In light of this general framework, a new mixed DG method with strongly imposed symmetry is proposed, and we apply it to solve linear elasticity problem with arbitrary order discontinuous finite element spaces.
