Limit Groups are Subgroup Conjugacy Separable

Group Theory 2016-05-17 v2

Abstract

A group GG is called subgroup conjugacy separable if for every pair of non-conjugate finitely generated subgroups of GG, there exists a finite quotient of GG where the images of these subgroups are not conjugate. We prove that limit groups are subgroup conjugacy separable. We also prove this property for one relator groups of the form R=a1,...,anWnR=\langle a_1,...,a_n\mid W^n\rangle with n>Wn>|W|. The property is also proved for virtual retracts (equivalently for quasiconvex subgroups) of hyperbolic virtually special groups.
