报告摘要:We construct a family of explicit tamed Euler--Maruyama (TEM) schemes, which can preserve the same Lyapunov structure for superlinear SODEs. These TEM schemes are shown to inherit the ergodicity of the considered SODEs and converge with optimal strong convergence orders. Then we generalize these results to Galerkin-based fully discrete TEM for a family of superlinear SPDEs (including the stochastic Allen--Cahn equation). We also present recent uniform weak convergence rates and/or estimates between invariant measures for superlinear SODEs and SPDEs.
