Shift invariance and reflexivity of compressions of multiplication operators
M. Cristina Câmara, Kamila Kliś-Garlicka, Bartosz Łanucha +1
The property of being shift invariant and being reflexive or transitive in the case of the space of (asymmetric) truncated Toeplitz operators, and the space of (asymmetric) dual tr…
Square roots of some classical operators
Javad Mashreghi, Marek Ptak, William T. Ross
In this paper we give complete descriptions of the set of square roots of certain classical operators, often providing specific formulas. The classical operators included in this d…
Intertwining property for compressions of multiplication operators
M. Cristina Câmara, Kamila Kliś--Garlicka, Bartosz Łanucha +1
Following Beurling's theorem the natural compressions of the multiplication operator in the classical space are compressions to model spaces and to their orthogonal complemen…
Asymmetric truncated Toeplitz operators and conjugations
M. Cristina Câmara, Kamila Kliś-Garlicka, Marek Ptak
Truncated Toeplitz operators in a model space are C--symmetric with respect to a natural conjugation in that space. We show that this and another conjugation associated to an ortho…
--normal operators
Marek Ptak, Katarzyna Simik, Anna Wicher
A new class of operators, larger than -symmetric operators and different than normal one, named --normal operators is introduced. Basic properties are given. Characterization…
Conjugations in
M. Cristina Câmara, Kamila Kliś--Garlicka, Bartosz Łanucha +1
Conjugations commuting with and intertwining and in , where is a Hilbert space, are characterize…
