Cubulated hyperbolic groups admit Anosov representations

Group Theory 2026-01-30 v1 Geometric Topology

Abstract

We prove that any hyperbolic group acting properly discontinuously and cocompactly on a CAT(0)\mathrm{CAT}(0) cube complex admits a projective Anosov representation into SL(d,R)\mathrm{SL}(d, \mathbb{R}) for some dd. More specifically, we show that if Γ\Gamma is a hyperbolic quasiconvex subgroup of a right-angled Coxeter group CC, then a generic representation of CC by reflections restricts to a projective Anosov representation of Γ\Gamma.
