COVARIANT DERIVATIVES OF THE BEREZIN TRANSFORM

摘要

Improving upon recent results of Coburn, Xia, Li, Eng11S" and Zhang, Bommier-Hato, and others, we give estimates for higher-order covari-ant derivatives of the Berezin transform of bounded linear operators on a reproducing kernel Hilbert space of holomorphic functions. The answer turns out to involve the curvature of the Bergman-type metric associated to the reproducing kernel.
