Rotation groups, mediangle graphs, and periagroups: a unified point of view on Coxeter groups and graph products of groups

Anthony Genevois

Published 2022-12-13Version 1

In this article, we introduce rotation groups as a common generalisation of Coxeter groups and graph products of groups (including right-angled Artin groups). We characterise algebraically these groups by presentations (periagroups) and we propose a combinatorial geometry (mediangle graphs) to study them. As an application, we give natural and unified proofs for several results that hold for both Coxeter groups and graph products of groups.
