Compactness and invariance properties of evolution operators associated with Kolmogorov operators with unbounded coefficients

Luciana Angiuli, Luca Lorenzi

In this paper we consider nonautonomous elliptic operators $\mathcal{A}$ with nontrivial potential term defined in $I\times {\mathbb{R}}^d$, where $I$ is a right-halfline (possibly $I…
