摘要：

Given a Banach algebra A and a is an element of A, several relations among the Drazin spectrum of a and the Drazin spectra of the multiplication operators L-a and R-a will be stated. The Banach space operator case will be also examined. Furthermore, a characterization of the Drazin spectrum will be considered. (C) 2009 Elsevier Inc. All rights reserved.
