Sometimes these recommendations.Hyperbolic groups are sometimes called word hyperbolic groups or negatively curved groups. A finite group is a trivial example of a hyperbolic group. Free groups of finite rank (cf. Free group ) and fundamental groups of compact Riemannian manifolds of negative sectional curvature (cf. Fundamental group; Riemannian manifold ) are hyperbolic.An important generalization of hyperbolic groups in geometric group theory is the notion of a relatively hyperbolic group.Motivating examples for this generalization are given by the fundamental groups of non-compact hyperbolic manifolds of finite volume, in particular, the fundamental groups of hyperbolic knots, which are not hyperbolic in the sense of Gromov.

In group theory, more precisely in geometric group theory, a hyperbolic group, also known as a word hyperbolic group or Gromov hyperbolic group, is a finitely generated group equipped with a word metric satisfying certain properties abstracted from classical hyperbolic geometry.The notion of a hyperbolic group was introduced and developed by Mikhail Gromov ().The theory of hyperbolic spaces was introduced by M. Gromov in (1, 2),. the study of Gromov hyperbolic graphs can shed light on the.. as hyperbolic groups have a soluble.

Groups and nonpositive curvature General references are the books by Brison and Hae iger (BH99) and by Ball-mann (Bal95). Apart from that there are some book projects on geometric group.

Let H be a properly discontinuous group of isometries of a negatively curved (Gromov hyperbolic) metric space X.We give equivalent conditions on H to be quasi-convex. The main application of this is to give alternate definitions of quasi-convex, or rational subgroups of negatively curved (word hyperbolic) groups.

Gromov's theory of hyperbolic groups have had a big impact in combinatorial group theory and has deep connections with many branches of mathematics suchdifferential geometry, representation theory, ergodic theory and dynamical systems. This book is an elaboration on some ideas of Gromov.

We consider the harmonic measure on the Gromov boundary of a nonamenable hyperbolic group defined by a finite range random walk on the group, and study the corresponding orbit equivalence relation.

Bio-Bibliography. Mikhael L. Gromov, born on 23 December, 1943, in Boksitogorsk, USSR, has been a naturalized French citizen since 1992. He obtained his Masters degree (1965), his Doctorate (1969) and his Post-doctoral Thesis (1973) from Leningrad University, where he had also been teaching from 1967 to 1974 as an Assistant Professor; from 1974 to 1981, he was Professor at the University of.

In continuation of (JOH04, OH07), we prove that existentially closed CSA-groups have the independence property. This is done by showing that there exist words having the independence property relative to the class of torsion-free hyperbolic groups.

Hyperbolic groups are a class of groups introduced by Gromov in 1987, which form an important part of geometric group theory. In Chapter 1, we give an introduction to this subject. In Chapter 2, we use the theory of complexes of groups to show that the integral homology and cohomology groups of a hyperbolic group are computable by a Turing machine.

Geometric ideas have played a very major role in the development of Group theory in 20th century. Coxeter groups and Coxeter complexes, Tits theory of buildings, Bass-Serre theory of Groups acting on trees, Gromov’s notion of hyperbolic groups and combinatorial methods have all been very central in several areas of mathe-matics.

Computing the Gromov Hyperbolicity of Graphs. This page provides a program implementing the exact algorithm described in () for computing the hyperbolicity of a graph, and a set of heuristics.The program is provided 'as is', with absolutely no warranty.

Module Overview. Students will be able to apply logic and reason to prove basic results in geometric group theory. They will be able to use the geometry of the hyperbolic plane and other related simple geometric artefacts to demonstrate many of the standard features of geometric group theory.

The field grew in part from the study of “wild” metric structures in study of Gromov hyperbolic groups, from attacks on Novikov conjecture and the related Baum-Connes conjecture.
