内容介绍:This talk is devoted to weak convergence analysis of an explicit full-discrete  scheme for additive noise driven SPDEs with non-globally Lipschitz coefficients.  A novel approach of weak convergence analysis is proposed and the expected weak  convergence rates are successfully obtained for an explicit time-steppping fully  discrete scheme. Numerical results are also provided to support our findings.  This talk is based on a joint work with Siqing Gan and Meng Cai.
