Title: Computing the Critical Dimensions of Bratteli-Vershik systems

Abstract: Critical dimension measures the growth rate of the sum of Radon-Nikodym derivatives. Critical dimension is invariant under metric isomorphism, and for non-singular systems it is shown to exhibit some characteristics of entropy. I will give a brief introduction to entropy theory of measure-preserving systems. Then I will explain how to calculate critical dimensions of Bratteli-Vershik systems. This is a joint work with Anthony Dooley.
