Under mild conditions on the characteristic exponent or the symbol of Lévy process, we derive explicit estimates forLp(dx) →Lq(dx) (1 ≤p≤q≤ ∞) norms of semigroups and their gradients of the associated Lévy driven Ornstein–Uhlenbeck process. Our result efficiently applies to the class of Lévy driven Ornstein–Uhlenbeck processes, where the asymptotic behaviour near infinity for the symbol of Lévy process is known.
