On the weak limit of compact operators on the reproducing kernel Hilbert space and related questions

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
By applying the so-called Berezin symbols method we prove a Gohberg- Krein type theorem on the weak limit of compact operators on the non- standard reproducing kernel Hilbert space which essentially improves the similar results of Karaev [5]: We also in ...

Introduction to the dynamical properties of Toeplitz operators on the Hardy space of the unit disc

Concrete Operators
These notes are based on a mini-course given at the ACOTCA conference 2025. The goal is to present full proofs of the first two key results regarding hypercyclic Toeplitz operators, in a way that is accessible to beginners.

Introduction to the spectral theory of Toeplitz operators

Concrete Operators
We provide a brief introduction to the spectral theory of Toeplitz operators on Hardy spaces built upon L p-spaces and their abstract generalisations.

Hyponormality on a weighted Bergman space of an annulus with a general harmonic symbol

Open Mathematics
In this work we consider the hyponormality of Toeplitz operators on the Bergman space of the annulus with a logarithmic weight. We give necessary conditions when the symbol is of the form φ+ψ̄ $\varphi +\bar{\psi }$ where both φ and ψ are analytic on ...

Commutants of the sum of two quasihomogeneous Toeplitz operators

Concrete Operators
A major open question in the theory of Toeplitz operator on the Bergman space of the unit disk of the complex plane is the complete characterization of the set of all Toeplitz operators that commute with a given operator.

Dual Toeplitz operators on the weighted Fock spaces

四川大学学报. 自然科学版
With the successful characterization of the semi-commutativity of dual Toeplitz operators on the orthogonal complement of the Bergman space over the unit disk， dual Toeplitz operators on the orthogonal complement of analytic function spaces have ...
