报告题目：Efficient algorithms for time fractional diffusion and wave equations

报 告 人：Prof. Xiaoping Xie, School of Mathematics, Sichuan University

报告摘要：We consider several numerical methods for time fractional diffusion and wave problems. The regularity of the weak solutions to the problems with nonsmooth data are investigated. For the time fractional diffusion problems, we analyze a time-stepping finite element method and a discontinuous Galerkin method. For the time fractional wave problems, we analyze three numerical methods, i.e. a time-spectral finite element method, a space-time finite element method, and a Petrov-Galerkin method. Stability and convergence of the algorithms are derived. Numerical experiments are performed to verify the theoretical results. This is joint work with Binjie Li and Hao Luo.
