Harmonic Analysis and Representation Theory for Groups Acting on Homogenous Trees - Alessandro Figa-Talamanca - Bog

These notes treat in full detail the theory of representations of the group of automorphisms of a homogeneous tree. The unitary irreducible representations are classified in three types: a continuous series of spherical representations; two special representations; and a countable series of cuspidal representations as defined by G.I. Ol'shiankii.
