Phase retrieval on circles and lines
I. Chalendar, J. R. Partington
Let and be analytic functions on the open unit disc such that on a set . We give an alternative proof of the result of Perez that there exists …
Linear isometries of Hol(D)
I. Chalendar, L. Oger, J. R. Partington
A complete characterisation is given of all the linear isometries of the Fréchet space of all holomorphic functions on the unit disc, when it is given one of the two standard metri…
A note on composition operators on model spaces
Isabelle Chalendar, Pavel Gumenyuk, John E. McCarthy
Motivated by the study of composition operators on model spaces launched by Mashreghi and Shabankha we consider the following problem: for a given inner function $ϕ\not\in\mathsf{A…
Subspaces of linearly homeomorphic to
Eric Amar, Bernard Chevreau, Isabelle Chalendar
We present two fast constructions of weak*-copies of in and show that such copies are necessarily weak*-complemented. Moreover, via a Paley-Wiener type…
Phragmén--Lindelöf principles for generalized analytic functions on unbounded domains
Isabelle Chalendar, Jonathan R. Partington
We prove versions of the Phragmén--Lindelöf strong maximum principle for generalized analytic functions defined on unbounded domains. A version of Hadamard's three-lines theorem is…
An extremal problem for characteristic functions
Isabelle Chalendar, Stephan Ramon Garcia, William T. Ross +1
Suppose is a subset of the unit circle and is the Hardy subalgebra. We examine the problem of finding the distance from the characterist…
