Quasi-conformal geometry and word hyperbolic Coxeter groups Marc Bourdon (joint work with Bruce Kleiner) Arbeitstagung, 11 june 2009 In [6] J. Heinonen and P. Koskela develop the theory of (analytic) mod- ulus in metric spaces, and introduce the notion of Loewner space. 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. 31, 59-115), gives the reader a bird’s eye view of this rich terrain. This book introduces and explains hyperbolic geometry and hyperbolic 3- and 2-dimensional manifolds in the first two chapters and then goes on to develop the subject. Generalizing to Higher Dimensions 67 6. Hyperbolic geometry Math 4520, Spring 2015 So far we have talked mostly about the incidence structure of points, lines and circles. This is a course of the Berlin Mathematical School held in english or deutsch (depending on the audience). The author discusses the profound discoveries of the astonishing features of these 3-manifolds, helping the reader to understand them without going into long, detailed formal proofs. Geometry today Metric space = any collection of objects + notion of “distance” between them Example 1: Objects = all continuous functions [0,1] → R Distance? There are three broad categories of geometry: flat (zero curvature), spherical (positive curvature), and hyperbolic (negative curvature). %���� Abstract . They build on the definitions for Möbius addition, Möbius scalar multiplication, exponential and logarithmic maps of . Rudiments of Riemannian Geometry 68 7. For the hyperbolic geometry, there are sev-eral important models including the hyperboloid model (Reynolds,1993), Klein disk model (Nielsen and Nock,2014) and Poincare ball model (´ Cannon et al.,1997).

Cannon, Floyd and Parry produced a mathematical growth model which demonstrated that some systems determined by simple finite subdivision rules can results in objects (in their example, a tree trunk) whose large-scale form oscillates wildly over time even though the local subdivision laws remain the same. Some facts that would apply to geodesics in hyperbolic geometry still hold for our geodesic bundles in a NWD.

Einstein and Minkowski found in non-Euclidean geometry a geometric basis for the understanding of physical time … We first discuss the hyperbolic plane. The geometry of a space goes hand in hand with how one defines the shortest distance between two points in that space. They review the wonderful history of non-Euclidean geometry. In geometric group theory, groups are often studied in terms of asymptotic properties of a Cayley graph of the group.
