A notion of quasiconvex subgroups in acylindrically hyperbolic groups

Group Theory 2025-10-06 v2

Abstract

In this paper, we present a notion of quasiconvexity in the setting of finitely-generated groups with hyperbolically embedded subgroups. Our main result shows that this notion yields uniform quasiconvex constants in the setting of coned-off cusped spaces. We also prove that this notion of quasiconvexity is preserved under sufficiently long Dehn filling. As an application, we generalize a theorem of Groves-Manning on groups acting on CAT(0)\operatorname{CAT}(0) cube complexes.
