Abstract:
Improving upon a recent result of L. Coburn and J. Xia, we show that for any bounded linear operator $T$ on the Segal-Bargmann space, the Berezin transform of $T$ is a function whose partial derivatives of all orders are bounded. Similarly, if $T$ is a bounded operator on any one of the usual weighted Bergman spaces on a bounded symmetric domain, then the appropriately defined “invariant derivatives” of any order of the Berezin transform of $T$ are bounded. Further generalizations are also discussed.References
