The -invariants of Thompson's group via Morse theory

Stefan Witzel, Matthew C. B. Zaremsky

Bieri, Geoghegan and Kochloukova computed the BNSR-invariants of Thompson's group for all . We recompute these using entirely geometric techniques, making use of th…

Finiteness Properties of Chevalley Groups over the Laurent Polynomial Ring over a Finite Field

Stefan Witzel

We show that if G is a Chevalley group of rank n and F_q[t,t^{-1}] is the ring of Laurent polynomials over a finite field, then G(F_q[t,t^{-1}]) is of type F_{2n-1}. This bound is…
