        题目: A finite element method for linear elliptic PDEs in non-divergence form

        报告摘要: In this talk I shall present a newly developed finite element method for approximating strong solutions of a class of linear elliptic PDEs in non-divergence form whose leading coefficients are only continuous.  Such PDEs are building blocks of fully nonlinear Hamilton-Jacobi-Bellman equations arising from stochastic optimal control and financial mathematics. The proposed method may be viewed as a C^0 DG method, it is very simple to implement and that can be done using any standard finite code. On the other hand, the convergence analysis of the method is quite involved and very technical, it requires to establish a (finite element) discrete Calderon-Zygmund theory, which will be the focus of this talk.  Numerical experiments will be presented to demonstrate the effectiveness of the proposed finite element method. If time permits, extensions to IP-DG methods will also be discussed.
