Expressions for the g-Drazin inverse in a Banach algebra
Huanyin Chen, Marjan Sheibani
We explore the generalized Drazin inverse in a Banach algebra. Let be a Banach algebra, and let . If then $a+b\in \mathcal{A}^{…

Additive properties of G-Drazin inverse of linear operators
Huanyin Chen, Marjan Sheibani
In this paper, we investigate additive properties of generalized Drazin inverse for linear operators in Banach spaces. Under new polynomial conditions on generalized Drazin inverti…
