On Weyl spectra of algebraically totally-paranormal operators

Jin Chun Kim

Semyung University

Abstract

In this paper we show that Weyl's theorem holds for $f(T)$ when an Hilbert space operator $T$ is ``algebraically totally-paranormal" and $f$ is any analytic function on an open neighborhood of the spectrum of $T$.

Keywords: Weyl's theorem, algebraically totally-paranormal operators
