Rings and Algebras 2020-04-20 v2

Abstract

Let nNn\in {\Bbb N}. An element aRa\in R has generalized n-strongly Drazin inverse if there exists xRx\in R such that xax=x,xcomm2(a),anaxRqnil.xax=x, x\in comm^2(a), a^n-ax\in R^{qnil}. For any a,bRa,b\in R, we prove that 1ab1-ab has generalized n-strongly Drazin inverse if and only if 1ba1-ba has generalized n-strongly Drazin inverse. Extensions in Banach algebra are also obtained.
