Title	Characterizing hyperbolicity via game theory
Speaker, Affiliation	Raphael Appenzeller, Universität Heidelberg

Abstract	The cop numbers are two new integer-valued invariants of finitely generated groups defined in terms of a two player pursuit game played on Cayley graphs. We use the cop numbers to give a new characterization of hyperbolic groups and virtually free groups. We discuss potential applications and recent progress on remaining open questions. This is joint work with Kevin Klinge.
