Kevin Wortman

We exhibit a family of infinite, finitely-presented, nilpotent-by-abelian groups. Each member of this family is a solvable S-arithmetic group that is related to Baumslag-Solitar gr…

Finiteness properties of arithmetic groups over function fields

Kai-Uwe Bux, Kevin Wortman

We determine when an arithmetic subgroup of a reductive group defined over a global function field is of type FP_\infty by comparing its large-scale geometry to the large-scale geo…
