Mathematics Kick-Off Colloquium by Prof. Bryna Kra, Northwestern University
Mathematics Kick-Off Colloquium by Prof. Bryna Kra, Northwestern University, “Periodicity and Complexity in One Dimension and Beyond” Live Monday, September 20, 1 – 1:50 pm, North Science Building 113
Abstract: One of the simplest behaviors that can arise in a dynamical system is existence of a periodic point, meaning a point that after finitely many steps returns to where it started, thus repeating the same behavior over and over. Sometimes such behavior can be detected by some local behavior based on some measurements of complexity. We will start by exploring this relation in one dimension, where this phenomenon is well understood. We then turn to higher dimensional versions and quickly arrive at current research and numerous open questions.
