Quantum harmonic analysis and the Differential operators on weighted Bergman spaces of bounded symmetric domains
Abstract
We develop quantum harmonic analysis (QHA) for operators on the parametrized Bergman space $\mathcal{A}^2_ν(Ω)$ of a bounded symmetric domain $Ω$, extending the theory previously known for the unit ball. Building on this framework, we introduce a class of differential operators acting on operators on $\mathcal{A}^2_ν(Ω)$. Combining these tools, we advance the theory of Toeplitz operators on $\mathcal{A}^2_ν(Ω)$: we establish Toeplitz approximation results via the $α$-Berezin transform, construct a differential operator $D_α$ that shifts the $α$-Berezin transform, and obtain several characterizations of the radial Toeplitz algebra -- including one via the uniformly continuous radial operators, and one via the domain of $D_α$.
