Almost Congruence Extension Property for subgroups of free groups

Group Theory 2017-10-24 v3

Abstract

In this paper we provide a sufficient condition for a subgroup of a free group not to have the almost congruence extension property (ACEP). We also show that any finitely generated subgroup of a free group satisfies some a generalization of ACEP.
