Title:Constructions in Infinite Ergodic Theory, TIME CHANGE: starts at 3:25pm
Seminar:Dynamical systems seminar
Speaker:Kelly Yancey, University of Maryland
Abstract:
In ergodic theory two properties that are very different, though not exclusive, are rigidity and weak mixing. In fact, these properties are typical. A natural question to ask is what happens if we consider systems that preserve an infinite measure, like Lebesgue measure on the positive reals. This is part of the set-up in infinite ergodic theory. During this talk we will discuss rigidity versus various types of weak mixing in infinite ergodic theory. We will also construct examples of transformations that have these desired properties. Our examples will be via the method of cutting and stacking. This is joint work with Rachel Bayless.
