Higman-Thompson groups and profinite properties of right-angled Coxeter groups
Samuel M. Corson, Sam Hughes, Philip Möller +1
We prove that every right-angled Coxeter group (RACG) is profinitely rigid amongst all Coxeter groups. On the other hand we exhibit RACGs which have infinite profinite genus amongs…

Profinite properties of Coxeter groups
Sam Hughes, Philip Möller, Philip Möller +1
We prove a number of results about profinite completions of Coxeter groups. For example we prove Coxeter groups are good in the sense of Serre and that various splittings of Coxete…

Profinite rigidity of Kähler groups: Riemann surfaces and subdirect products
Sam Hughes, Claudio Llosa Isenrich, Pierre Py +2
This paper establishes strong profinite rigidity results for Kähler groups, showing that certain groups are determined within the class of residually finite Kähler groups by thei…
