Perturbation of Toeplitz operators and reflexivity

Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2014
It was shown that the space of Toeplitz operators perturbated by finite rank operators is 2-hyperreflexive.

Products of Several Toeplitz Operators

Journal of Functional Analysis, 2000
Let \(a\in L^\infty\) and \(T_a:H^2\to H^2\) be a Toeplitz operator with symbol \(a\) acting in Hardy space \(H^2\) on the unit disk. The author describes the necessary and sufficient conditions on symbols \(a_j\) of Toeplitz operators \(T_{a_j}\) when the identity \(T_{a_1}T_{a_2}\dots T_{a_n}=T_{a}\), \(a=a_1a_2\dots a_n\), holds for an arbitrary \(n\

On the induced connection on sections of Toeplitz operators

Modern Mathematical Methods
The purpose of the present article is to show that an upper bound of the induced connection on sections of Toeplitz operators is bounded by a function of the Hankel and of the Toeplitz operators on a weighted Hilbert Bergman space on a bounded domain of ...

Toeplitz Operators, Kähler Manifolds, and Line Bundles

Symmetry, Integrability and Geometry: Methods and Applications, 2007
This is a survey paper. We discuss Toeplitz operators in Kähler geometry, with applications to geometric quantization, and review some recent developments.
