Hyperbolically embedded subgroups and quasi-isometries of pairs
arXiv:2202.00536 · doi:10.4153/S0008439523000012
Abstract
We give technical conditions for a quasi-isometry of pairs to preserve a subgroup being hyperbolically embedded. We consider applications to the quasi-isometry and commensurability invariance of acylindrical hyperbolicity of finitely generated groups.
