Weyl type theorems for hypercyclic, supercyclic, and Toeplitz operators

Abstract

In this paper, we study property $(U{W}_E)$ for hypercyclic and supercyclic operators. The stability of variants of Weyl type theorems under compact perturbations for Toeplitz operators on the Bergman space is also studied. We also provide some examples of Toeplitz operators satisfying Weyl type theorems on the Bergman space and the harmonic Bergman space.
