Commuting Toeplitz and small Hankel operators on the Bergman space
This paper shows that on the Bergman space of the open unit disk, the Toeplitz operator \(T_{{\overline{p}}+\varphi }\) and the small Hankel operator \(\Gamma _\psi\) commute only in the obvious cases, where \(\varphi\) and \(\psi\) are both bounded analytic functions, and p is an analytic polynomial.
