The unitary highest weight modules for G = U(1, q ), which occur as irreducible subrepresentations of the oscillator representation on a Fock space F, can each be realized on a space of polynomial‐valued functions over the bounded realization B q of G / K . This is achieved via an integral transform constructed by L. Mantini. A decomposition of these representations into K ‐types is given, including an explicit description of how Mantini's transform behaves on K ‐types. An inverse is produced for the transform, thus giving unitary structures for the geometric realizations of the unitary highest‐weight modules over G / K . 1991 Mathematics Subject Classification : 22E45, 22E70.
