摘要：The finite difference method and the finite element method are two main methods for numerical solutions of partial differential equations. Although these methods have been well developed, some fundamental problems remained unsolved.
In this talk we are concerned with elliptic equations of second order on domains with nonsmooth boundaries. The solutions for nonsmooth domains often do not have full regularity. In such a case, the optimal order of convergence in the L2-norm by the finite element method was not known. We demonstrate that substantial techniques from approximation theory can be used to solve such fundamental problems.
