Lecture 2 will be at 4pm. Lecture 3 will be at 5:30pm. These follow the introductory talk on Monday at 4pm in SERC 110A.

We will present connections between recent research in dynamical systems and the classical theory of elliptic curves and rational points. On the dynamical side – specifically in the study of iteration of rational functions (Julia sets, bifurcations, the Mandelbrot set), but originating in the mathematical study of planetary motion – the first connections were observed about 100 years ago. On the arithmetic side, it was probably the 1960s when dynamical ideas were first used as tools to understand the arithmetic geometry of elliptic curves and higher-dimensional varieties. The goal is to provide examples of how these relationships developed and where they have brought us today. More information: < sep2019/Grosswald2019.pdf>. Temple campus map: <>.
