Group actions on buildings, lattices and Kac-Moody groups
Friday 1st August, 12:05-12:55pm,
Carslaw 175.
We will discuss a group associated to a Kac-Moody Lie algebra over a
finite field, as constructed by Tits and Carbone-Garland. Such a group
is locally compact and totally disconnected and admits an action on
its Bruhat-Tits building, which in rank 2 is a homogeneous tree. We
also discuss the existence of lattice subgroups in the Kac-Moody
group.
