On New Approach to semi-Fredholm theory in unital C*-algebras
Stefan Ivkovic
Axiomatic Fredholm theory in unital C*-algebras was established by Keckic and Lazovic in [15]. Following the purely algebraic approach by Keckic and Lazovic, in [14] we extended fu…
On New Approach to Fredholm theory in unital C*-algebras
Stefan Ivkovic
Motivated by the Fredholm theory on the standard Hilbert module over an unital C*-algebra introduced by Mishchenko and Fomenko, we provide a new approach to axiomatic Fredholm theo…
On Drazin invertible C*-operators and generalized C*-Weyl operators
Stefan Ivkovic
In this paper, we obtain several extensions of semi-Fredholm theory on Hilbert modules by generalizing in this setting their classical counterparts regarding Weyl operators and Dra…
Hypercyclic Operators on Hilbert C*-modules
Stefan Ivkovic
In this paper, we characterize hypercyclic generalized bilateral weighted shift operators on the standard Hilbert module over the C*-algebra of compact operators on the separable H…
