Hypercontractivity and asymptotic behaviour in nonautonomous Kolmogorov equations

L. Angiuli, L. Lorenzi, A. Lunardi

We consider a class of nonautonomous second order parabolic equations with unbounded coefficients defined in $I \times R^{d}$ , where $I$ is a right-halfline. We prove logarithmic Sobo…

Compactness and asymptotic behavior in nonautonomous linear parabolic equations with unbounded coefficients in $R^{d}$

Alessandra Lunardi

We consider a class of second order linear nonautonomous parabolic equations in R^d with time periodic unbounded coefficients. We give sufficient conditions for the evolution opera…

On the Dirichlet semigroup for Ornstein -- Uhlenbeck operators in subsets of Hilbert spaces

Giuseppe Da Prato, Alessandra Lunardi

We consider a family of self-adjoint Ornstein--Uhlenbeck operators $L_{α}$ in an infinite dimensional Hilbert space H having the same gaussian invariant measure $μ$ for all $α\in [0…
