Title: Robust Mechanisms for Chaos

Abstract: What are the underlying mechanisms for robustly chaotic behavior in smooth dynamics? In addressing this question, I will focus on the study of diffeomorphisms of a compact manifold, where "chaotic" means "mixing" and and "robustly" means "stable under smooth perturbations." I will describe recent advances in constructing and using tools called "blenders" to produce stably chaotic behavior with arbitrarily little effort.

Amie Wilkinson (University of Chicago): Prof. Amie Wilkinson received her BA from Harvard and her Ph.D. from the University of California at Berkeley. After a post-doc at Harvard, she became a professor at North­ western University, where she stayed 13 years, before moving to the University of Chicago in 2012. Prof. Wilkinson is a leading researcher in ergodic theory and dynamical sys­ tems. Among other recognitions of her many achievements, she was an invited speaker at the International Congress of Mathematicians in 2010, was awarded the Satter Prize in Mathematics in 2011, and was elected a fellow of the AMS in 2014. Prof. Wilkinson has also been very active in public outreach, giving numerous public lectures, interviews, and recently publishing an article in the New York Times.
