報(bào)告內(nèi)容： In this talk we consider long time dynamics of a randomly perturbed non-autonomous coupled system , whose  coordinate satisfies a semilinear parabolic equation with an additive noise, and  coordinate satisfies a differential equation whose solutions do not converge too rapidly. The noise is either the white noise induced by a Brownian motion  or a stationary process whose integral is approximating . After addressing certain assumptions for such system, we show that for (resp. ) with respect to the noise  (resp. integral of  there exists a invariant manifold which is exponentially attracting any other solution outside it. Also, as  tends to 0, the invariant manifold and its derivative in  for the case  are approaching to those for .
