A remark on Berezin's quantization and cut locus

The consequences for Berezin's quantization on symmetric spaces of the identity of the set of coherent vectors orthogonal to a fixed one with the cut locus are stated precisely. It is shown that functions expressing the coherent states, the covariant symbols of operators, the diastasis function, the characteristic and two-point functions are defined when one variable does not belong to the cut locus of the other one.Comment: 8 pages, Latex2e, ams fonts, to appear in "Quantizations, Deformations and Coherent States", Edited by S.
