报告摘要In this talk, a system of stochastic delayed  reaction-diffusion equations with multiplicative noise and deterministic non-autonomous forcing on thin domain  are considered. We first prove the existence and uniqueness of bi-spatial pullback attractor for these equations. Then upper semicontinuity of the global random attractors in the delay is obtained as the length of time delay approaches zero. Finally, we establish the upper semicontinuity of these attractors when a family of (n+1)-dimensional thin domains collapses onto an n-dimensional domain.
