New additive results for the generalized Drazin inverse in a Banach algebra
Xiaoji Liu, Xiaolan Qin, Julio Benítez · Filomat · 2016
In this paper, we investigate additive properties of the generalized Drazin inverse in a Banach algebra A. We find explicit expressions for the generalized Drazin inverse of the sum a + b, under new conditions on a,b ? A.
