Induced representations from the Heisenberg parabolic subgroup of $SL(n+2,\mathbb{R})$

Abstract

The group $G=SL(n+2,\mathbb{R})$ has a parabolic subgroup $P=MAN$ whose unipotent radical is a Heisenberg group. We study representations induced from a character of $P$, and using the Lie algebra action on the space of $K$-finite vectors we find the points of reducibility and the complementary series. We identify solutions to the conformally invariant systems of differential operators as subrepresentations.
