Characterization of truncated Toeplitz operators by conjugations
Kamila Kliś-Garlicka, Bartosz Łanucha, Marek Ptak
Truncated Toeplitz operators are C--symmetric with respect to the canonical conjugation given on an appropriate model space. However, by considering only one conjugation one cannot…
Characterizations of asymmetric truncated Toeplitz operators
Cristina Câmara, Joanna Jurasik, Kamila Kliś--Garlicka +1
The aim of this paper is to investigate asymmetric truncated Toeplitz operators with symbols between two different model spaces given by inner functions such that one divides…
--hyperreflexivity and hyporeflexivity of power partial isometries
Kamila Piwowarczyk, Marek Ptak
Power partial isometries are not always hyperreflexive neither reflexive. In the present paper it will be shown that power partial isometries are always hyporeflexive and --hype…
Skew-symmetric operators and reflexivity
Chafiq Benhida, Kamila Kliś-Garlicka, Marek Ptak
In contrast to the subspaces of all -symmetric operators, we show that the subspaces of all skew-C symmetric operators are reflexive and even hyperreflexive with the constant $κ…
