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…
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…
Invertibility, Fredholmness and kernels of dual truncated Toeplitz operators
M. Cristina Câmara, Kamila Kliś-Garlicka, Bartosz Łanucha +1
Asymmetric dual truncated Toeplitz operators acting between the orthogonal complements of two (eventually different) model spaces are introduced and studied. They are shown to be e…
Conjugations in and their invariants
M. Cristina Câmara, Kamila Kliś--Garlicka, Bartosz Łanucha +1
Conjugations in space of the unit circle commuting with multiplication by or intertwining multiplications by and are characterized. We also study their behav…
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…
