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…
