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.
