Regularizing properties of (non-Gaussian) transition semigroups in Hilbert spaces

D. A. Bignamini, S. Ferrari

Let $\mathcal{X}$ be a separable Hilbert space with norm $\Vert \cdot \Vert$ and let $T>0$. Let $Q$ be a linear, self-adjoint, positive, trace class operator on $\mathcal{X}$, let $F:\math…
