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…
