Conjugations in L2 and their invariants
Maria Cristina Câmara , Kamila Kliś-Garlicka , Bartosz Łanucha , Marek Ptak
AbstractConjugations in space L2 of the unit circle commuting with multiplication by z or intertwining multiplications by z and z¯ are characterized. We also study their behaviour with respect to the Hardy space, subspaces invariant for the unilateral shift and model spaces.
