The Laplacian of an operator and the radial Toeplitz algebra

V Dewage, M Mitkovski - Journal of Mathematical Analysis and Applications, 2025 - Elsevier
Using tools from quantum harmonic analysis, we show that the domain of the Laplacian of
an operator is dense in the Toeplitz algebra over the Fock space F 2 (C n). As an …

C*-algebra generated by horizontal Toeplitz operators on the Fock space

K Esmeral, N Vasilevski - Boletín de la Sociedad Matemática Mexicana, 2016 - Springer
We introduce the so-called horizontal Toeplitz operators acting on the Fock space and give
an explicit description of the C*-algebra generated by them. We show that any Toeplitz …

Radial Toeplitz operators on the Fock space and square-root-slowly oscillating sequences

Eigenvalue characterization of radial operators on weighted Bergman spaces over the unit ball

W Bauer, CH Yanez, N Vasilevski - Integral Equations and Operator …, 2014 - Springer
We study the so-called radial operators, and in particular radial Toeplitz operators, acting on
the standard weighted Bergman space on the unit ball in C^ n C n. They turn out to be …

Commutative algebras of Toeplitz operators on the Bergman space revisited: spectral theorem approach

G Rozenblum, N Vasilevski - Integral Equations and Operator Theory, 2022 - Springer
For three standard models of commutative algebras generated by Toeplitz operators in the
weighted analytic Bergman space on the unit disk, we find their representations as the …

Toeplitz operators on the Fock space with quasi-radial symbols

V Dewage, G Ólafsson - Complex Analysis and Operator Theory, 2022 - Springer
Abstract The Fock space F (C n) is the space of holomorphic functions on C n that are
square-integrable with respect to the Gaussian measure on C n. This space plays an …
