Pseudo semi B-Fredholm and Generalized Drazin invertible operators Through Localized SVEP

Abdelaziz Tajmouati, Mohamed Karmouni, Mbark Abkari

In this paper, we define and study the pseudo upper and lower semi B-Fredholm of bounded operators in a Banach space. In particular, we prove equality up to $S(T)$ between the left…
