## Abstract

For $$p$$ odd, the Lie group $$G^\sharp =\mathrm{SO}_0(p+1,p+1)$$ has a family of complementary series representations realized on the space of real $$(p+1)\times (p+1)$$ skew symmetric matrices, similar to the Stein’s complementary series for $$\mathrm{SL}(2n, {\mathbb C})$$. We consider their restriction on the subgroup $$G_0=\mathrm{SO}_0(p+1,p)$$ and prove that they are still irreducible and is equivalent to (a unitarization of) the principal series representation of $$G=\mathrm{SO}(p+1, p)$$, and also irreducible under a maximal parabolic subgroup of $$G$$.
