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…

Dynamical properties and some classes of non-porous subsets

Stefan Ivkovic, Serap Oztop, Seyyed Mohammad Tabatabaie

In this paper, we introduce several classes of non-σ-porous subsets of a general Lebesgue space. Also, we study some linear dynamics of operators and show that the set of all non-h…

Hypercyclic Generalized Shift Operators

Stefan Ivkovic, Seyyed Mohammad Tabatabaie

In this paper, we study the linear dynamical properties of shift operators on some classes of Segal algebras. Moreover, we characterize hypercyclic generalized bilateral shift oper…
