Dynamics Seminar: Joshua Frisch (École Normale Supérieure) - Automorphism groups of low complexity subshifts

Tue, 06/12/202212:00-13:00
In this talk I will discuss a new criterion for amenability of a group based on the idea of partial actions. As an application I will show a conjecture of Cyr and Kra, namely that every 0 entropy minimal subshift has an amenable automorphism group.
