Complex Symmetric Toeplitz Operators

Integral Equations and Operator Theory, 2021
The paper is devoted to study the complex symmetry for Toeplitz operators, with certain trigonometric symbols, over the Hardy space \(H^2\) of the unit circle \(\mathbb{T}\). A~bounded operator \(T\) on a Hilbert complex space is said to be complex symmetric (respectively, canonically symmetric) operator if there is a conjugation (respectively ...

Toeplitz Operators

2023
AbstractThis chapter surveys Toeplitz operators Tφ : H2 → H2, Tφf = P + (φf), on the Hardy space H2, where φ ∈ L∞(T) and P+ is the orthogonal projection of L2(T) onto H2. We examine the matrix representations of these operators, their spectral properties, and a characterization of them related to the unilateral shift.

Toeplitz Operators on Dirichlet Spaces

Acta Mathematica Sinica, English Series, 2001
Let \(B_n\) be the unit ball in \(\mathbb{C}^n\) and \(\mathcal{D}\) the Dirichlet space, that is, the subspace of analytic functions in the Sobolev space with the norm \[ \left[\sum_{i=1}^n\int_{B_n}\left(\left|\frac{\partial f}{\partial z_i}(z)^2+ \frac{\partial f}{\partial \overline{z_i}}(z)^2 \right|\right) dv\right]^\frac{1}{2}.
