觀點(diǎn)綜述：In thistalk,we study 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.
