Localization and Toeplitz Operators on Polyanalytic Fock Spaces
Localization operators polyanalytic Fock spaces Toeplitz operators Gel’fand-Shilov spaces

Abstract: The well know conjecture of {\it Coburn} [{\it L.A. Coburn, {On the Berezin-Toeplitz calculus}, Proc. Amer. Math. Soc. 129 (2001) 3331-3338.}] proved by {\it Lo} [{\it M-L. Lo, {The Bargmann...
Quasihomogeneous Toeplitz operators on the harmonic Bergman space
Toeplitz operator harmonic Bergman space quasihomogeneous symbol Mellin transform
2011/9/15
Abstract: In this paper we study the product of Toeplitz operators on the harmonic Bergman space of the unit disk of the complex plane C. Mainly, we discuss when the product of two quasihomogeneous To...
On lower eigenvalue estimates for Toeplitz operators with radial symbols in Bergman spaces
Bergman spaces Bargmann spaces Toeplitz operators
2011/2/21
We consider Toeplitz operators in different Bergman type spaces, having radial symbols with variable sign. We show that if the symbol has compact support or decays rapidly, the eigenvalues of such ope...

Toeplitz operators Bergman spaces of polyanalytic functions
2011/1/21
We study algebraic properties of Toeplitz operators on Berg-man spaces of polyanalytic functions on the unit disk. We obtain results on finite-rank commutators and semi-commutators of Toeplitz operato...
Boundary values in range spaces of co-analytic truncated Toeplitz operators

Functions in backward shift invariant subspaces have nice analytic continuation properties outside the spectrum of the inner function defining the space. Inside the spectrum of the inner function.

We examine when two maximal abelian algebras in the truncated Toeplitz operators are spatially isomorphic. This builds upon recent work of N. Sedlock, who obtained a complete description of the maxima...
We find necessary and sufficient conditions for the product of two truncated Toeplitz operators on a model space to itself be a truncated Toeplitz operator, and as a result find a characterization for...
We consider three problems connected with coinvariant sub-spaces of the backward shift operator in Hardy spaces Hp:– properties of truncated Toeplitz operators;– Carleson-type embedding theorems for t...
Commuting dual Toeplitz operators on the polydisk

2007/12/13
On the polydisk, the commutativity of dual Toeplitz operators is studied. We obtain characterizations of commuting dual Toeplitz operators, essentially commuting dual Toeplitz operators and essentiall...
