Essential commutants and characterizations of the Toeplitz algebra [PDF]

Journal of operator theory, 2020
We study the Toeplitz algebra which is generated by Toeplitz operators with bounded symbols on the Fock space Fpα. We show that the Toeplitz algebra coincides with each of the algebras generated by band-dominated, sufficiently localized and weakly ...

Toeplitz Operators on the Weighted Pluriharmonic Bergman Space with Radial Symbols

Abstract and Applied Analysis, 2011
We construct an operator R whose restriction onto weighted pluriharmonic Bergman Space bμ2(Bn) is an isometric isomorphism between bμ2(Bn) and l2#. Furthermore, using the operator R we prove that each Toeplitz operator Ta with radial symbols is unitary ...

Toeplitz Operators whose Symbols Are Borel Measures

Journal of Function Spaces, 2021
In this paper, we are concerned with Toeplitz operators whose symbols are complex Borel measures. When a complex Borel measure μ on the unit circle is given, we give a formal definition of a Toeplitz operator Tμ with symbol μ, as an unbounded linear ...

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

Abstract 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

Properties of two variables Toeplitz type operators

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2016
The investigation of properties of generalized Toeplitz operators with respect to the pairs of doubly commuting contractions (the abstract analogue of classical two variable Toeplitz operators) is proceeded. We especially concentrate on the condition of

Berezin–Toeplitz quantization associated with higher Landau levels of the Bochner Laplacian [PDF]

Journal of Spectral Theory, 2020
In this paper, we construct a family of Berezin-Toeplitz type quantizations of a compact symplectic manifold. For this, we choose a Riemannian metric on the manifold such that the associated Bochner Laplacian has the same local model at each point (this ...

Algebraic and spectral properties of H-Toeplitz operators on the Bergman space

AIMS Mathematics
In this paper, we discuss the zero product problem of two H-Toeplitz operators and the commuting problem of H-Toeplitz and Hankel operators on the Bergman space.

Commuting Toeplitz operators and H-Toeplitz operators on Bergman space

AIMS Mathematics
In this paper, we consider the H-Toeplitz and Toeplitz operators acting on the Bergman space. First, we describe the characterizations of commutativity of two H-Toeplitz operators with certain harmonic symbols.

Toeplitz matrix completion via a low-rank approximation algorithm

Journal of Inequalities and Applications, 2020
In this paper, we propose a low-rank matrix approximation algorithm for solving the Toeplitz matrix completion (TMC) problem. The approximation matrix was obtained by the mean projection operator on the set of feasible Toeplitz matrices for every ...
