The function-operator convolution algebra over the Bergman space of the ball and its Gelfand theory

Vishwa Dewage, Robert Fulsche, Gestur Ólafsson

We investigate the structure of the commutative Banach algebra formed as the direct sum of integrable radial functions on the disc and the radial operators on the Bergman space, en…

Toeplitz algebra of bounded symmetric domains: A quantum harmonic analysis approach via localization

Vishwa Dewage

We prove that Toeplitz operators are norm dense in the Toeplitz algebra over the weighted Bergman space of a bounded symmetric domai…

A quantum harmonic analysis approach to the Berger-Coburn theorem

Vishwa Dewage, Mishko Mitkovski

We use quantum harmonic analysis for densely defined operators to provide a simplified proof of the Berger-Coburn theorem for boundedness of Toeplitz operators. In addition, we rev…

Quantum Harmonic Analysis on the Unweighted Bergman Space of the Unit Ball

Matthew Dawson, Vishwa Dewage, Mishko Mitkovski +1

We study quantum harmonic analysis (QHA) on the Bergman space over the unit ball in . We formulate a Wiener's Tauberian theorem, and cha…

On the density of Toeplitz operators in the Toeplitz algebra over the Bergman space of the unit ball

Vishwa Dewage, Mishko Mitkovski

We use quantum harmonic analysis and representation theory to provide a new proof of Xia's theorem: "Toeplitz operators are norm dense in the Toeplitz algebra over the Bergman spac…

The Laplacian of an operator and the radial Toeplitz algebra

Vishwa Dewage, Mishko Mitkovski

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 $\mathcal{F}^2(\mathbb{C}^n…
