Spectral and resonance problem for perturbations of periodic Jacobi operators

Rostyslav Kozhan

Necessary and sufficient conditions are presented for a measure to be the spectral measure of a finite range or exponentially decaying perturbation of a periodic Jacobi operator. A…

L1-spectrum of Banach space valued Ornstein-Uhlenbeck operators

Rostyslav Kozhan

We characterize the $L^{1} (E; μ_{\infty})$ -spectrum of the Ornstein-Uhlenbeck operator, where $μ_{\infty}$ is the invariant measure for the Ornstein-Uhlenbeck semigroup. The main result c…
