Drazin spectra of Banach space operators and Banach algebra elements

Functional Analysis 2013-07-29 v1

Abstract

Given a Banach Algebra AA and aAa\in A, several relations among the Drazin spectrum of aa and the Drazin spectra of the multiplication operators LaL_a and RaR_a will be stated. The Banach space operator case will be also examined. Furthermore, a characterization of the Drazin spectrum will be considered.
