Toeplitz operators on Bergman spaces of polygonal domains

Abstract

We study the boundedness of Toeplitz operators with locally integrable symbols on Bergman spaces $A^p(\Omega ),$ $1<p<\infty ,$ where $\Omega \subset \mathbb{C}$ is a bounded simply connected domain with polygonal boundary. We give sufficient conditions for the boundedness of generalized Toeplitz operators in terms of "averages" of symbol over certain Cartesian squares. We use the Whitney decomposition of $\Omega$ in the proof. We also give examples of bounded Toeplitz operators on $A^p(\Omega )$ in the case where polygon $\Omega$ has such a large corner that the Bergman projection is unbounded.
