Profinite properties of algebraically clean graphs of free groups

Group Theory 2023-12-27 v1

Abstract

We prove that for every prime pp algebraically clean graphs of groups are virtually residually pp-finite and cohomologically pp-complete. We also prove that they are cohomologically good. We apply this to certain 22-dimensional Artin groups.
