Published 23 Jan 2015 in math.RT and math.GR | (1501.05820v2)

Abstract: We show that the group $PSL(2,R)$ is a spherical subgroup in the group of $C^{3$-diffeomorphisms} of the circle. Also, the group of automorphisms of a Bruhat--Tits tree is a spherical subgroup in the group of hierarchomorphisms of the tree.
