Abstract:Abstract. In this paper we close the cases that were left open in our earlier works on the study of conformally invariant systems of second-order differential operators for degenerate principal series. More precisely, for these cases, we find the special values of the systems of differential operators, and determine the standardness of the homomorphisms between the generalized Verma modules, that come from the conformally invariant systems.
“…We close these cases in [22] together with the case when q is of type D n (n − 2). When q is of type B n (n − 1), the special constituent V (μ + nγ ) is of type 1b, and when q is of type C n (i), the special constituent V (μ + γ ) is of type 3.…”

In this paper we construct conformally invariant systems of first order and second order differential operators associated to a homogeneous line bundle L s → G 0 /Q 0 with Q 0 a maximal parabolic subgroup of quasi-Heisenberg type. This generalizes the results by Barchini, Kable, and Zierau. To do so we use techniques different from ones used by them.

“…Higher order case is still in development. For some recent studies, see, for instance, Barchini-Kable-Zierau [2,3], Kable [21,22,23,24,25, 26], Kobayashi-Ørsted-Somberg-Souček [36], and the first author [43,44].…”
In this paper we give Peter-Weyl type formulas for the space of K-finite solutions to intertwining differential operators between degenerate principal series representations. Our results generalize a result of Kable for conformally invariant systems. The main idea is based on the duality theorem between intertwining differential operators and homomorphisms between generalized Verma modules. As an application we uniformly realize on the solution spaces of intertwining differential operators all small representations of SL(3, R) attached to the minimal nilpotent orbit.2010 Mathematics Subject Classification. 22E46, 17B10.
