Algebraic properties of Toeplitz operators on annulus and multiply connected domains
Sayan Adhikari, Susmita Das
Abstract
We study the Toeplitz operators on the Hardy space over the annulus and provide a complete characterization of them. Based on that, we single out a certain class of Toeplitz operators that satisfy the multiplicativity property and lead to a zero product theorem. We further extend the results for the general multiply-connected domain and prove the zero product theorem for Toeplitz operators on the Hardy space over such a domain.
