Abstract:

A basic question in dynamical systems is when are two systems

isomorphic. Starting from rotations of the circle and flows on tori I will

talk about the fact that typical interval exchanges and flows on flat

surfaces are not isomorphic. In fact, they satisfy a stronger property

called being disjoint. I will mention some consequences of these results

and open questions. This includes joint work with Vaibhav Gadre and Pascal

Hubert.
