摘要:In this talk, we will first introduce the theory of pullback attractors of non-autonomous random dynamical systems. Then we will study the Wong-Zakai approximations of the stochastic reaction-diffusion equations and wave equations by a stationary process as an approximation of the white noise. For a class of nonlinear diffusion terms, we prove the existence and uniqueness of pullback attractors of the approximation equation, which are upper semicontinuous for linear multiplicative and additive noise.
