The drazin spectrum in banach algebras

WebIn this talk results on isolated spectral points, group, Drazin and Koliha-Drazin invertible elements in the context of quotient Banach algebras or in ranges of (not necessarily continuous) homomorphism between complex unital Banach algebras will be presented. The case of Calkin algebras on Banach and Hilbert spaces will be also studied.

WebNov 1, 2009 · Actually, several well-known results concerning the Drazin spectrum of Banach space operators will be extended to the frame of Banach algebras. 2. Preliminary definitions and results From now on, X will denote a Banach space and L (X) will be the Banach algebra of all operators defined on and with values in X. WebIn Section 2 we introduce our definitions of spectrum and spectral radius and we focus on a set of elements called tame which play a role comparable to bounded operators on a Banach space. In the Section 3 we examine in more detail the relation of our present concepts to some known results in Banach algebras. manga cleaner jobs https://horseghost.com
