Linear dynamics of cosine operator functions on solid Banach function spaces
Seyyed Mohammad Tabatabaie, Stefan Ivkovic
In this paper, we give some sufficient and necessary conditions for cosine operator functions on solid Banach function spaces to be chaotic or topologically transitive.
On generalized spectra in C*-algebras of operators over C*-algebras
Stefan Ivkovic
In this paper we consider shift operators, self-adjoint, unitary and normal operators on the standard module over a unital C*-algebra A. We define various generalized spectra in A…
On compressions and generalized spectra of operators over C*-algebras
Stefan Ivkovic
In the classical operator theory, there are several versions of spectra, related to special classes of operators (Fredholm, semi-Fredholm, upper/lower semi-Fredholm,etc.). We gener…
On generalizations of semi-Fredholm operators over C*-algebras
Stefan Ivkovic
Starting from the definition of A-Fredholm and semi-A-Fredholm operator on the standard module over a unital C*- algebra A, introduced in [8] and [4], we construct various generali…
Semi-Fredholm Theory on Hilbert C*-modules
Stefan Ivkovic
In this paper we establish the semi-Fredholm theory on Hilbert C*-modules as a continuation of Fredholm theory on Hilbert C*-modules established by Mishchenko and Fomenko. We give…
On operators with closed range and semi-Fredholm operators over W*-algebras
Stefan Ivkovic
In this paper we consider A-Fredholm and semi-A-Fredholm operators on Hilbert C*-modules over a W*-algebra A defined in [3],[10]. Using the assumption that A is a W*-algebra (and n…
