On the spectral identities and fundamental properties of one-sided Drazin inverses in Banach algebras
Kai Yan
We establish several fundamental properties of one-sided (generalized) Drazin inverses in Banach algebras, including intertwining properties and reverse order laws. In particular,…

One-sided Drazin inverses in Banach algebras and perturbations of B-Fredholm spectra
Kai Yan
The famous Drazin inverse and generalized Drazin inverse were introduced by Drazin in 1958 and Koliha in 1996, respectively. In the present paper, the author introduces the concept…
