B. Orsted et G. Zhang, REPRODUCING KERNELS AND COMPOSITION SERIES FOR SPACES OF VECTOR-VALUED HOLOMORPHIC-FUNCTIONS, Pacific journal of mathematics, 171(2), 1995, pp. 493-510
We calculate the norm of each K-type in a vector-valued Hilbert space
of holomorphic functions on a tube domain of type I. As a consequence
we get composition series of the analytic continuation of certain holo
morphic discrete series and an expansion relative to K of the matrix-v
alued reproducing kernel.
