B-Fredholm Spectra of Drazin Invertible Operators and Applications

E Aponte, J Macías, J Sanabria, J Soto - Axioms, 2021 - mdpi.com
In this article, we consider Drazin invertible operators for study of the relationship between
their B-Fredholm spectra and the transfer between some of the spectral properties defined
through B-Fredholm spectra of this class of operators. Among other results, we investigate
the transfer of generalized a-Weyl's theorem from T to their Drazin inverse S, if it exists.
