When 1 → H → G → Q → 1 is a short exact sequence of three word-hyperbolic groups, Mahan Mj (formerly Mitra) has shown that the inclusion map from H to G extends continuously to a map between the Gromov boundaries of H and G.This boundary map is known as the Cannon–Thurston map. The latter has a particularly comprehensive bibliography. Hyperbolic geometry of the Poincaré ball The Poincaré ball model is one of five isometric models of hyperbolic geometry Cannon et al.

James Weldon Cannon (* 30.Januar 1943 in Bellefonte, Pennsylvania) ist ein US-amerikanischer Mathematiker, der sich mit hyperbolischen Mannigfaltigkeiten, geometrischer Topologie und geometrischer Gruppentheorie befasst.. Cannon wurde 1969 bei Cecil Edmund Burgess an der University of Utah promoviert (Tame subsets of 2-spheres in euclidean 3-space). Further dates will be available in February 2021.

Cannon, Floyd, and Parry first studied finite subdivision rules in an attempt to prove the following conjecture: Cannon's conjecture: Every Gromov hyperbolic group with a 2-sphere at infinity acts geometrically on hyperbolic 3-space. Bibliography PRINT. In 1980s the focus of Cannon's work shifted to the study of 3-manifold s, hyperbolic geometry and Kleinian group s and he is considered one of the key figures in the birth of geometric group theory as a distinct subject in late 1980s and early 1990s.
