Invariant measures and the Kolmogorov equation for the stochastic fast diffusion equation (Q981025)

The authors deal with the transition semigroup associated with the fast diffusion equation in a bounded domain of \(\mathbb{R}^d\), perturbed by a Gaussian noise and prove the existence of an invariant measure. They also study the Kolmogorov infinitesimal generator and study the respective Sobolev space.
