Subprincipal Symbol for Toeplitz Operators [PDF]

open access: yesLetters in Mathematical Physics, 2016
We establish some subprincipal estimates for Berezin-Toeplitz operators on symplectic compact manifolds. From this, we construct a family of subprincipal symbol maps and we prove that these maps are the only ones satisfying some expected conditions.

k-quasi-homogeneous Toeplitz operators on pluriharmonic Bergman space of the unit ball

open access: yes四川大学学报. 自然科学版, 2019
In this paper, we study some basic properties of k-quasi-homogeneous Toeplitz operators on the pluriharmonic Bergman space of the unit ball, and obtain the symmetric properties of the commutator and semi-commutator consisting of two such operators.

On the closed range problem for composition operators on the Dirichlet space

open access: yesConcrete Operators, 2019
We characterize closed range composition operators on the Dirichlet space for a particular class of composition symbols. The characterization relies on a result about Fredholm Toeplitz operators with BMO1 symbols, and with Berezin transforms of vanishing

Factorization of Hankel operators, range inclusion of Toeplitz and Hankel operators on the vector-valued Hardy space

open access: yesComptes Rendus. Mathématique
Using Douglas theorem on factorization and range inclusion of bounded linear operators, we give the factorization of Hankel operators, range inclusion of Hankel and Toeplitz operators defined on vector-valued Hardy spaces.

Block Toeplitz operators with frequency-modulated semi-almost periodic symbols

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
This paper is concerned with the influence of frequency modulation on the semi-Fredholm properties of Toeplitz operators with oscillating matrix symbols.

Binormal Toeplitz operators on the Hardy space

open access: yes, 2019
We characterize binormal Toeplitz operators with analytic, or, coanalytic symbol functions. Furthermore, for a large class of nonanalytic, noncoanalytic Toeplitz operators which include Toeplitz operators with trigonometric or rational symbols, we prove ...

Toeplitz Operators on the Weighted Bergman Space over the Two-Dimensional Unit Ball

open access: yesJournal of Function Spaces, 2015
We extend the known results on commutative Banach algebras generated by Toeplitz operators with radial quasi-homogeneous symbols on the two-dimensional unit ball.

Density of Toeplitz operators in rotation-invariant Toeplitz algebras

open access: yesJournal of Fourier Analysis and Applications
Abstract We use results and techniques from Werner’s “quantum harmonic analysis” to show that G-invariant Toeplitz operators on $$\mathcal {F}^2$$ F 2

Small Toeplitz Operators

open access: yes, 2018
Toeplitz operators acting on Hilbert spaces of analytic functions are among the most well studied examples of concrete operators. In our work we are interested in a cut-off property of such operators; namely, if the operator is small enough, does it have
