I strongly urge readers to read this piece to get a flavor of the quality of exposition that Cannon commands. The geometry of a space goes hand in hand with how one defines the shortest distance between two points in that space. Introduction Non-Euclidean, or hyperbolic, geometry was created in the first half of the nineteenth century in the midst of attempts to understand Euclid's axiomatic basis for geometry. Physical Review D 85: 124016. Stereographic … (elementary treatment). The aim of this section is to give a very short introduction to planar hyperbolic geometry.

The diagram on the left, taken from Cannon-Floyd-Kenyon-Parry’s excellent introduction to Hyperbolic Geometry in Flavors of Geometry (MSRI Pub. In order to determine these curvatures for the hyperbolic tilings considered in this paper we make use of the Poincaré disc model conformal mapping of the two-dimensional hyperbolic plane with curvature − 1 onto the Euclidean unit disc Cannon et al.

Hyperbolic Geometry JAMES W. CANNON, WILLIAM J. FLOYD, RICHARD KENYON, AND WALTER R. PARRY Contents 1. 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.
