A new characterization of generalized Browder’s theorem and a cline’s formula for generalized Drazin-eromorphic inverses

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 Drazinmeromorphic spectrum. Also, wegeneralize Cline?s formula to the case of generalized Drazin-meromorphic invertibility under the assumption that AkBkAk = Ak+1 for some positive integer k.
