Abstract
Let M = G/K be a Hermitian symmetric space of the non-compact type and let π be a discrete series representation of G which is holomorphically induced from a unitary irreducible representation ρ of K. We define and we study a notion of Berezin symbol for operators acting on the space of π. In particular, we give explicit formulas for the Berezin symbols of the representation operators \({\pi(g) (g\in G)}\) and dπ(X) (X in the Lie algebra of G). Moreover, we construct an adapted Weyl correspondence for π in the sense of Cahen (Differ Geom Appl 25:177–190, 2007). This generalizes the results already obtained in the case when ρ is a unitary character of K, see Cahen (Beiträge Algebra Geom 51:301–311, 2010).
