Dynamics, Geometry and Combinatorics  21 - 25 October 2019

Part of the Semester : Dynamics with Structures

Room : GA 3 21

Organisers

Anders Karlsson, Université de Genève, Uppsala University

Bryna Kra, Northwestern University

Omri Sarig, Weizmann Institute for Science

This workshop brings together dynamicists who use techniques from, and are motivated by, combinatorics, geometry, and number theory.  The topics cover a broad swath of dynamics, including ergodic theory, homogeneous dynamics, symbolic dynamics, Teichmuller theory, and billiards, and the aim of the workshop is to highlight the common features across these subjects.
