Group actions on buildings, lattices and KacMoody groups

Carslaw 175.
We will discuss a group associated to a KacMoody Lie algebra over a
finite field, as constructed by Tits and CarboneGarland. Such a group
is locally compact and totally disconnected and admits an action on
its BruhatTits building, which in rank 2 is a homogeneous tree. We
also discuss the existence of lattice subgroups in the KacMoody
group.
