Klappentext The ICM 2010 satellite conference 'Geometry! Topology and Dynamics in Negative Curvature' afforded an excellent opportunity to discuss various aspects of this fascinating interdisciplinary subject in which methods and techniques from geometry! topology! and dynamics often interact in novel and interesting ways. Containing ten survey articles written by some of the leading experts in the field! this proceedings volume provides an overview of important recent developments relating to negative curvature. Topics covered include homogeneous dynamics! harmonic manifolds! the Atiyah Conjecture! counting circles and arcs! and hyperbolic buildings. Each author pays particular attention to the expository aspects! making the book particularly useful for graduate students and mathematicians interested in transitioning from other areas via the common theme of negative curvature. Zusammenfassung Negative curvature arises in several mathematical areas! including geometry! topology! dynamics! and number theory. This volume contains survey articles around this common theme! which should help mathematicians interested in transitioning between these areas! as well as graduate students entering this interdisciplinary subject.
