SPECTRAL CONTINUITY OF ESSENTIALLY p-HYPONORMAL OPERATORS
Kim, An-Hyun; Kwon, Eun-Young;

Abstract
In this paper it is shown that the spectrum $\small{{\sigma}}$ is continuous at every p-hyponormal operator when restricted to the set of essentially p-hyponormal operators and moreover $\small{{\sigma}}$ is continuous when restricted to the set of compact perturbations of p-hyponormal operators whose spectral pictures have no holes associated with the index zero.
