Conformal dimension and Gromov hyperbolic groups with 2–sphere boundary

Mario Bonk and Bruce Kleiner

Geometry & Topology 9 (2005) 219–246

DOI: 10.2140/gt.2005.9.219

Abstract

Suppose G is a Gromov hyperbolic group, and ∂ G is quasisymmetrically homeomorphic to an Ahlfors Q–regular metric 2–sphere Z with Ahlfors regular conformal dimension Q. Then G acts discretely, cocompactly, and isometrically on H3.

Keywords

Gromov hyperbolic groups, Cannon's conjecture, quasisymmetric maps
