Ey. Leung et T. Tonthat, ON A MULTIPLICITY FORMULA OF WEIGHTS OF REPRESENTATIONS OF SO-ASTERISK(2N) AND RECIPROCITY THEOREMS FOR SYMPLECTIC GROUPS, Proceedings of the American Mathematical Society, 123(4), 1995, pp. 1281-1288
A formula relating the multiplicity of a weight of a holomorphic discr
ete series of the group SO(2n) to the frequency of occurrence of an i
rreducible holomorphically induced representation of the group Sp(2n,
C) in an n-fold tenser product of irreducible symmetric representation
s of Sp(2n, C) is given. Reciprocity theorems relating holomorphic dis
crete series of SO(2n) (resp. Sp(2n, R)) to holomorphically induced r
epresentations of Sp(2k,C) (resp. SO(N, C)) are also derived.
