Title: Sumner Myers Prize: Developments in entropy theory
Abstract: Within the field of dynamics, entropy is a real-valued isomorphism invariant which measures the amount of chaos or complexity in certain systems. It was first introduced by Kolmogorov in 1958 for measure-preserving actions of the integers on probability spaces, and then extended to actions of countable amenable groups in 1975. Following a surprising breakthrough by Lewis Bowen in 2008, a new research program now centers on extending entropy theory to actions of non-amenable groups. In this talk, I will review some of the history of classical entropy theory, motivate this new research program, and mention some recent results.
