报告题目：Weak convergence of path-dependent SDEs with irregular coefficients

报告人：鲍建海 副教授

报告摘要：In this talk we develop via Girsanov's transformation a perturbation argument to investigate weak convergence of Euler-Maruyama (EM) scheme for path-dependent SDEs with  Holder continuous drifts. This approach is available to other scenarios, e.g., truncated EM schemes for non-degenerate SDEs with finite memory or infinite memory. Also, such a trick can be applied to study weak convergence  of truncated EM scheme for a range of stochastic Hamiltonian systems with irregular coefficients and with memory. Moreover, the weak convergence of path-dependent SDEs under integrability condition is investigated by establishing, via the dimension-free Harnack inequality, exponential integrability of irregular drifts w.r.t. the invariant probability measure constructed explicitly in advance. This is a joint work with Professor Jinghai Shao.
