Square integrability of regular representations on reductive homogeneous spaces

Kazushi Maeda, Yoshiki Oshima

Let $G$ be a real reductive Lie group and $H$ a reductive subgroup of $G$ . Benoist-Kobayashi studied when $L^{2} (G / H)$ is a tempered representation of $G$ and in particular they gave…

Restriction of irreducible unitary representations of Spin(N,1) to parabolic subgroups

Gang Liu, Yoshiki Oshima, Jun Yu

In this paper, we obtain explicit branching laws for all irreducible unitary representations of $\Spin(N,1)$ restricted to a parabolic subgroup $P$ . The restriction turns out to be…
