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 Drazin-meromorphic spectrum. Also, we generalize Cline's formula to the case of generalized Drazin-meromorphic invertibility under the assumption that A k B k A k = A k+1 for some positive integer k
