Abstract
In the chapters 4, 6 and 7 we have proved that the semigroup Pt corresponding to the system du(t) = [Au(t)+F(u(t))]dt + Qdw(t), u(0) = x, (8.0.1) has a regularizing effect both in E and in H. Here we apply these results to the proof of the existence of a unique invariant measure μ, for the semigroup P t, which is equivalent to all transition probabilities P t(x,.), t > 0 and x ∈ H, and which is concentrated on the space of continuous functions E.
