The 2018-19 Hayden-Howard lecture 

Speaker: Laura DeMarco Department of Mathematics, Northwestern University
Time and location: Thursday, 11 April 2019, 3:30 pm. 106 Whitehall Classroom Building
Title: Complex Dynamics and Arithmetic Equidistribution

Abstract: I will explain a notion of arithmetic equidistribution that has recently found application in the study of complex dynamical systems.  It was first introduced about 25 years ago, by Szpiro-Ullmo-Zhang, to analyze the geometry and arithmetic of abelian varieties.  In 2011, Matt Baker and I used the theory to study periodic points of maps on P^1.  In this talk, I will explain some dynamical questions that were inspired by questions about elliptic curves, and then how the dynamical results allowed us to solve problems in the original setting of abelian varieties.  The new results are joint with Holly Krieger and Hexi Ye.

About the Hayden-Howard lecture

The Hayden-Howard lecture was inaugurated in the spring of 2001 by a generous contribution from a friend of the Department of Mathematics. The lecture series was established in honor of mathematics professors Thomas Hayden and Henry Howard. Each year, the lecture series brings a research mathematician of international stature to the University of Kentucky.
