Abstract: The discontinuous Galerkin method has attracted tremendous amount of attentions in the last decades since it has been applied to problems with regular solutions, the 2nd order elliptic equation for example. In spite of its well-known advantages, the efficiency of discontinuous Galerkin method for problems with very regular solutions is a weak point which has often been attacked at. In this talk, I will showthat the discontinuous Galerkin method may go beyond the continuous finite element method in efficiency for elliptic problems, where is the traditional area for the finite element method to outperform. Our technique to help DG out is to construct a brand-new approximate space which will be clarified in my talk.
