Abstract
We consider the spherical complementary series of rank one Lie groups H n= SO 0n 1 mathbb F for mathbb F=mathbb R mathbb C mathbb H We prove that there exist finitely many discrete components in its restriction under the subgroup H n1= SO 0n1 1 mathbb F This is proved by imbedding the complementary series into analytic continuation of holomorphic discrete series of G n=SUn 1 SUn 1times SUn 1 and SU2n 2 and by the branching of holomorphic representations under the corresponding subgroup G n1
