On Koliha-Drazin invertible operators and Browder type theorems
Miloš D. Cvetković, Snežana Č. Živković-Zlatanović
Let be a bounded linear operator on a Banach space . We give new necessary and sufficient conditions for to be Drazin or Koliha-Drazin invertible. All those conditions h…

Generalized Drazin-meromorphic invertible operators and generalized Kato-meromorphic decomposition
Snežana Č. Živković-Zlatanović, Bhagwati P. Duggal
A bounded linear operator on a Banach space is said to be generalized Drazin-meromorphic invertible if there exists a bounded linear operator acting on such that $T…

Pseudo-B-Fredholm operators, poles of the resolvent and mean convergence in the Calkin Algebra
Mohammed Berkani, Snežana Č. Živković-Zlatanović
We define here a pseudo B-Fredholm operator as an operator such that 0 is isolated in its essential spectrum, then we prove that an operator is pseudo- B-Fredholm if and only i…
