Quasi-Fredholm spectrum and compact perturbations

Anuradha Gupta, Ankit Kumar

In this paper we explore some characteristics of the quasi-Fredholm resolvent set $ρ_{q f} (T)$ of an operator $T$ defined on an infinite dimensional Banach space $X$ . Moreover, in t…

A new characterization of generalized Browder's theorem and a Cline's formula for generalized Drazin-meromorphic inverses

Anuradha Gupta, Ankit Kumar

In this paper, we give a new characterization of generalized Browder's theorem by considering equality between the generalized Drazin-meromorphic Weyl spectrum and the generalized…
