Partially Isometric Toeplitz Operators [PDF]

open access: yesProceedings of the American Mathematical Society, 1965
It has been observed that the only Toeplitz operators that are isometric are those of the form To where q is an inner function on the unit disc (see e.g., [1, Theorem 8, Corollary 3]; the notation and terminology introduced there will be adhered to throughout this note).

Toeplitz Operators on the Dirichlet Space of 𝔹n

open access: yesAbstract and Applied Analysis, 2012
We study the algebraic properties of Toeplitz operators on the Dirichlet space of the unit ball 𝔹n. We characterize pluriharmonic symbol for which the corresponding Toeplitz operator is normal or isometric.

Toeplitz Operators with IMOs Symbols between Generalized Fock Spaces

open access: yesJournal of Function Spaces, 2021
In this paper, we study the mapping properties of Toeplitz operators Tf associated with IMOs  symbols f acting between two generalized Fock spaces Fφp, where ...

Localized Frames and Compactness [PDF]

open access: yes, 2015
We introduce the concept of weak-localization for generalized frames and use this concept to define a class of weakly localized operators. This class contains many important operators, including: Short Time Fourier Transform multipliers, Calderon ...

Quasinormality and Numerical Ranges of Certain Classes of Dual Toeplitz Operators

open access: yesAbstract and Applied Analysis, 2010
The study of dual Toeplitz operators was elaborated by Stroethoff and Zheng (2002), where various corresponding algebraic and spectral properties were established.

On the Commutativity of a Certain Class of Toeplitz Operators

open access: yesConcrete Operators, 2014
One of the major goals in the theory of Toeplitz operators on the Bergman space over the unit disk D in the complex place C is to completely describe the commutant of a given Toeplitz operator, that is, the set of all Toeplitz operators that commute with

Algebraic Properties of Quasihomogeneous and Separately Quasihomogeneous Toeplitz Operators on the Pluriharmonic Bergman Space

open access: yesAbstract and Applied Analysis, 2013
We study some algebraic properties of Toeplitz operator with quasihomogeneous or separately quasihomogeneous symbol on the pluriharmonic Bergman space of the unit ball in ℂn. We determine when the product of two Toeplitz operators with certain separately

Toeplitz Operators on Dirichlet-Type Space of Unit Ball

open access: yesAbstract and Applied Analysis, 2014
We construct a function u in L2Bn, dV which is unbounded on any neighborhood of each boundary point of Bn such that Toeplitz operator Tu is a Schatten p-class ...

Toeplitz Operators with Quasihomogeneous Symbols on the Bergman Space of the Unit Ball

open access: yesJournal of Function Spaces and Applications, 2012
We consider when the product of two Toeplitz operators with some quasihomogeneous symbols on the Bergman space of the unit ball equals a Toeplitz operator with quasihomogeneous symbols.
