Ping-Pong, Automata and Stability for Hyperbolic Group Actions
Wednesday, September 28, 2022
4:00-5:30 PM
3866 East Hall Map
The ping-pong lemma is a well-known and ubiquitous tool in group theory. In this talk, I will discuss applications of some variations of the ping-pong lemma, involving the machinery of finite-state automata. These variations provide a technique for proving stability results about actions of arbitrary hyperbolic and relatively hyperbolic groups - even those which do not split as free products.
