Toeplitz operators on the proper images of bounded symmetric domains (2405.08002v1)

Abstract: Let $\Omega$ be a bounded symmetric domain in $\mathbb C^n$ and $f :\Omega \to \Omega^\prime$ be a proper holomorphic mapping factored by (automorphisms) a finite complex reflection group $G.$ We define an appropriate notion of the Hardy space $H^2(\Omega^\prime)$ on $\Omega^\prime$ which can be realized as a closed subspace of an $L^2$-space on the \v{S}ilov boundary of $\Omega^\prime$. We study various algebraic properties of Toeplitz operators (such as the finite zero product property, commutative and semi-commutative property etc.) on $H^2(\Omega^\prime)$. We prove a Brown-Halmos type characterization for Toeplitz operators on $H^2(\Omega^\prime),$ where $\Omega^\prime$ is an image of the open unit polydisc in $\mathbb C^n$ under a proper holomorphic mapping factored by an irreducible finite complex reflection group.
