Finiteness Properties of Chevalley Groups over the Ring of (Laurent) Polynomials over a Finite Field

Stefan Witzel

In these notes we determine the finiteness length of the groups G(O_S) where G is an F_q-isotropic, connected, noncommutative, almost simple F_q-group and O_S is one of F_q[t], F_q…

Higher finiteness properties of reductive arithmetic groups in positive characteristic: the rank theorem

Kai-Uwe Bux, Ralf Köhl, Stefan Witzel

We show that the finiteness length of an $S$ -arithmetic subgroup $Γ$ in a noncommutative isotropic absolutely almost simple group $G$ over a global function field is one less than…
