摘要:In this talk, an abstract method is presented to show that  upper semicontinuity  of  invariant measures of  dissipative dynamical systems  on  thin domains.  The abstract method presented can be used to many  physical systems.  As an example, we consider reaction-diffusion equations  on  thin domains. To this end,  we first  show  the   existence  of invariant measures of  the  equations in a bounded domain in $\R^{n+1}$ which can be viewed as a perturbation of  a bounded domain in $\R^n$. We then  prove  that any limit  of invariant measures of the  perturbed systems  must be an invariant measure of the limiting  system when the thin domains collapses.
