Zeros of optimal polynomial approximants in
Raymond Cheng, William T. Ross, Daniel Seco
The study of inner and cyclic functions in spaces requires a better understanding of the zeros of the so-called optimal polynomial approximants. We determine that a poin…
The Smirnov class for de Branges--Rovnyak spaces
Emmanuel Fricain, Andreas Hartmann, William T. Ross +1
Using an explicit construction, we show that the de Branges-Rovnyak spaces , corresponding to rational , are contained in their associated Smirnov classes.
Interpolating with outer functions
Javad Mashreghi, Marek Ptak, William T. Ross
The classical theorems of Mittag-Leffler and Weierstrass show that when is a sequence of distinct points in the open unit disk $\D$, with no accumulation points in $\D$,…
Inner vectors for Toeplitz operators
Raymond Cheng, Javad Mashreghi, William T. Ross
In this paper we survey and bring together several approaches to obtaining inner functions for Toeplitz operators. These approaches include the classical definition, the Wold decom…
Inner functions in reproducing kernel spaces
Raymond Cheng, Javad Mashreghi, William T. Ross
In this paper we explore the notion of inner function in a broader context of operator theory.
Multipliers between range spaces of co-analytic Toeplitz operators
Emmanuel Fricain, Andreas Hartmann, William T. Ross +1
In this paper we discuss the multipliers between range spaces of co-analytic Toeplitz operators.
