题目:Asymptotics of Multiscale Stochastic Systems

摘要:In this talk we mainly present some asymptotic results for a class of multiscale stochastic systems, more precisely, we will show some strong averaging principle, large deviations principle and central limit type theorems for multiscale SPDEs and DDS(P)DEs.

学术报告二

题目:Random dynamics of 3D BBM equations driven by nonlinear colored noise on unbounded domains

摘要:We are concerned with the long term behavior of the solutions of the non-autonomous Benjamin-Bona-Mahony equation driven by nonlinear colored noise with continuous coefficients defined on three-dimensional unbounded channels. We first prove the measurability of the multivalued random system by the idea of weak upper semicontinuity of solutions, and then establish the existence and uniqueness of tempered pullback random attractors based on the pullback asymptotic compactness of solutions. The difficulty of the non-compactness of Sobolev embeddings on unbounded domains is overcome by the methods of the spectral decomposition inside bounded domains as well as the uniform tail-estimates of solutions outside bounded domains. Furthermore, the upper semi-continuity of the random attractors with respect to external parameter and internal parameter have also been considered.This talk is based on joint works with Bixiang Wang(New Mexico Technology), Renhai Wang(Guizhou Normal University) and Xuping Zhang(Northwest Normal University).
