Unique product groups and congruence subgroups

Group Theory 2020-09-25 v3

Abstract

We prove that a uniform pro-p group with no nonabelian free subgroups has a normal series with torsion-free abelian factors. We discuss this in relation to unique product groups. We also consider generalizations of Hantzsche-Wendt groups.
