Coherent and precoherent operators
(Универзитет у Нишу, Природно-математички факултет, 13-12-2016)
In this thesis we introduce and investigate new classes of operators
which we call coherent and precoherent operators. These operators
appear as solutions of some problems in the literature, but they also
represent a ...
Kato type decompositions and generalizations of Drazin invertibility
(Универзитет у Нишу, Природно-математички факултет, 11-10-2017)
The main objective of this dissertation is to give necessary and
sufficient conditions under which a bounded linear operator T can be
represented as the direct sum of a nilpotent (quasinilpotent, Riesz)
operator TN and ...
