Division in group rings of surface groups

Geometric Topology 2021-01-05 v1 Group Theory Rings and Algebras

Abstract

We prove a division algorithm for group rings of high genus surface groups and use it to show that some 22-complexes with surface fundamental groups are standard. We also give an application of division to cohomological dimension of 22-relator groups acting on Hn\mathbb H^n.
