内容介绍：This talk is devoted to our recent progresses in numerical analysis of SDEs with non-globally Lipschitz coe?icients. Both implicit and explicit schemes are considered for SDEs under global monotonicity conditions, with strong convergence rates revealed. Positivity-preserving schemes are also considered for some practical SDE models and the strong approximation error analysis is reported. Finally, we look at numerical analysis of SDEs under non-global monotonicity conditions. This is based on a joint work with Lei Dai and Jiayi Wu.
