摘要:
        Since early 1970s, the superconvergence study of finite element methods has been a very active research topic due to its applications in leading to more efficient numerical methods for solving various differential equations. Many excellent superconvergence results have been obtained for elliptic equations, parabolic equations and linear hyperbolic equations. For Maxwell's equations, the first superconvergence result was derived until 1994. Since then, some results have been obtained. But there are many unsolved problems. In this talk, I'll present our recent breakthrough results obtained for rectangular (and cubic) edge elements from the first order to third order, and lowest order triangular and tetrahedron edge element. Theoretical analysis and numerical results will be presented. I will conclude the talk with some open issues.
