Abstract

Let X=G* be a compact Hermitian symmetric space. We study the Berezin transform on L2(X) and calculate its spectrum under the decomposition of L2(X) into the irreducible representations of G*. As applications we find the expansion of powers of the canonical polynomial (Bergman reproducing kernel for the canonical line bundle) in terms of the spherical polynomials on X, and we find the irreducible decomposition of tensor products of Bergman spaces on X.
