Abstract

We characterize the L1(E;μ)L^1(E;\mu_\infty)-spectrum of the Ornstein-Uhlenbeck operator, where μ\mu_\infty is the invariant measure for the Ornstein-Uhlenbeck semigroup. The main result covers the general case of an infinite-dimensional Banach space E under the assumption that the point spectrum of drift operator AA^* is nonempty. This extends several recent related results.
