Abstract
In this paper, we extend Jacobson’s lemma for Drazin inverses to the generalized n-strong Drazin inverses in a ring, and prove that 1−ac is generalized n-strong Drazin invertible if and only if 1−ba is generalized n-strong Drazin invertible, provided that a(ba)2 = abaca = acaba = (ac)2a. In addition, Jacobson’s lemma for the left and right Fredholm op-erators, and furthermore, for consistent in invertibility spectral property and consistent in Fredholm and index spectral property are investigated.
