Query: On the homomorphisms between the generalized Verma modules arising from
  conformally invariant systems   It is shown by Barchini, Kable, and Zierau that conformally invariant systems
of differential operators yield explicit homomorphisms between certain
generalized Verma modules. In this paper we determine whether or not the
homomorphisms arising from such systems of first and second order differential
operators associated to maximal parabolic subalgebras of quasi-Heisenberg type
are standard.
