The tree lattice existence theorems

A tree lattice is a discrete subgroup of finite covolume in
the automorphism group of a locally finite tree. In analogy with the
existence of lattice subgroups of real and padic Lie groups, H. Bass
and A. Lubotzky conjectured the existence of tree lattices. We outline
a complete proof of the BassLubotzky conjectures and give some
applications.
