A geometric proof that SL_2(Z[t,t^-1]) is not finitely presented
Kai-Uwe Bux, Kevin Wortman
We give a new proof of the theorem of Krstic-McCool from the title. Our proof has potential applications to the study of finiteness properties of other subgroups of SL_2 resulting…

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…

Quasi-isometric rigidity of higher rank S-arithmetic lattices
Kevin Wortman
We show that S-arithmetic lattices in semisimple Lie groups with no rank one factors are quasi-isometrically rigid.
