Abstract
We consider the multiplicity problem of the branching rule GL(2k, C) d own Sp(2k, C). Finite-dimensional irreducible representations of GL(2k , C) are realized as right translations on subspaces of the holomorphi c Hilbert (Bargmann) spaces of q x 2k complex variables. Maps are exhi bited which carry an irreducible representation of Sp(2k, C) into thes e subspaces. An algebra of commuting operators is constructed and it i s shown how eigen-values of certain of these operators can be used to resolve the multiplicity.
