Query: Invariant trilinear forms for spherical degenerate principal series of
  complex symplectic groups   We compute generalized Bernstein-Reznikov integrals associated with standard
complex symplectic forms by studying Knapp-Stein intertwining operators between
spherical degenerate principal series of complex symplectic groups.
