On the generalized Drazin inverse of the sum in a Banach algebra
Abstract
The objective of this paper is to study the existence of the generalized Drazin inverse of the sum a + b of two generalized Drazin invertible elements in a Banach algebra and present explicit expressions for the generalized Drazin inverse of this sum, under new conditions.
Key words: Generalized Drazin inverse, additive properties, Banach algebras.
