Building lattices and zeta functions

Anton Deitmar, Ming-Hsuan Kang, Rupert McCallum

We introduce the notion of a building lattice generalizing tree lattices. We give a Lefschetz formula and apply it to geometric zeta functions. We further generalize Bass's approac…

Free subgroups of special linear groups

Rupert McCallum

We present a proof of the following claim. Suppose that $n$ is an integer such that $n > 1$ and that $k$ is any field. Suppose that $g$ is an element of $SL (n, k)$ of infinit…

Rigidity of the group topology for closed Weyl transitive groups of automorphisms of a regular locally finite building

Rupert McCallum

We prove that if $G$ is a group of automorphisms of a regular locally finite building which is closed in the compact-open topology and acts Weyl transitively on the building, then…
