Generalized Cline's Formula for G-Drazin Inverse

Abstract

Let $R$ be an associative ring with an identity and suppose that $a,b,c,d\in R$ satisfy $bdb=bac,dbd=acd$. If $ac$ has generalized Drazin ( respectively, pseudo Drazin, Drazin) inverse, we prove that $bd$ has generalized Drazin (respectively, pseudo Drazin, Drazin) inverse. In particular, as applications, we obtain new common spectral properties of bounded linear operators over Banach spaces.
