Asymmetric truncated Toeplitz operators and Toeplitz operators with matrix symbol [PDF]

open access: yesJournal of Operator Theory, 2017
Truncated Toeplitz operators and their asymmetric versions are studied in the context of the Hardy space $H^p$ of the half-plane for ...

On Quasisimilarity for Toeplitz Operators [PDF]

open access: yesCanadian Mathematical Bulletin, 1985
AbstractIn this article we give a sufficient condition for quasisimilar analytic Toeplitz operators to be unitarily equivalent. We also use a result of Deddens and Wong to give a sufficient condition for an operator intertwining two analytic Toeplitz operators to intertwine their inner parts too.

Toeplitz versus Hankel: semibounded operators [PDF]

open access: yesOpuscula Mathematica, 2018
Our goal is to compare various results for Toeplitz \(T\) and Hankel \(H\) operators. We consider semibounded operators and find necessary and sufficient conditions for their quadratic forms to be closable. This property allows one to define \(T\) and \(

Dual Toeplitz Operators on Bounded Symmetric Domains [PDF]

open access: yesMathematics
We give some characterizations of dual Toeplitz operators acting on the orthogonal complement of the Bergman space over bounded symmetric domains. Our main result characterizes those finite sums of products of Toeplitz operators that are themselves dual ...

m-Isometric block Toeplitz operators [PDF]

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we study m-isometric block Toeplitz operators with trigonometric symbols. In addition, we give a necessary and sufficient condition for block Toeplitz operators with trigonometric polynomial symbols to be m-contractive.

Toeplitz Operators with Analytic Symbols [PDF]

open access: yesThe Journal of Geometric Analysis, 2020
We provide asymptotic formulas for the Bergman projector and Berezin-Toeplitz operators on a compact K{ä}hler manifold. These objects depend on an integer N and we study, in the limit N $\rightarrow$ +$\infty$, situations in which one can control them up to an error O(e^{-cN}) for some c > 0.

On Compactness of Products of Toeplitz Operators. [PDF]

open access: yesComplex Anal Oper Theory
Abstract We study compactness of product of Toeplitz operators with symbols continuous on the closure of the polydisc in terms of behavior of the symbols on the boundary. For certain classes of symbols f and g, we show that $$T_fT_g$$

Schatten class generalized Toeplitz operators on the Bergman space [PDF]

open access: yes, 2021
summary:Let $\mu $ be a finite positive measure on the unit disk and let $j\geq 1$ be an integer. D. Suárez (2015) gave some conditions for a generalized Toeplitz operator $T_{\mu }^{(j)}$ to be bounded or compact.
