Virtually Fibering Right-Angled Coxeter Groups

Group Theory 2021-07-01 v1

Abstract

We show that certain right-angled Coxeter groups have finite index subgroups that quotient to Z\mathbb Z with finitely generated kernels. The proof uses Bestvina-Brady Morse theory facilitated by combinatorial arguments. We describe a variety of examples where the plan succeeds or fails. Among the successful examples are the right-angled reflection groups in H4\mathbb H^4 with fundamental domain the 120120-cell or the 2424-cell.
