# Kieval Lecture Series

**VIRTUAL KIEVAL LECTURE SERIES**

# We are happy to announce that the Kieval Lecture has been rescheduled. Please join us on April 1st, 2021 for the first (and hopefully only) virtual Kieval Lecture

**UPDATE 3/4/2021 - Due to an unforeseen circumstance the lecture for today has been cancelled. It will be rescheduled at a future date. Professor Thurston sends his deepest apologies, and looks forward to rescheduling the event in the near future.**

The Kieval Lecture Series is funded through a bequest of the late Dr. Harry S. Kieval ’36, a longtime professor of mathematics at Humboldt State University in Arcata, California, who died in 1994. In addition to this lecture series, his estate provides funding to Cornell University for a similar lecture in physics, as well as annual prizes awarded to outstanding seniors in both mathematics and physics.

**Current and Upcoming Lectures**

April 1st, 2021 at 4:00 p.m. - Due to an unforeseen circumstance the Kieval Lecture has been cancelled. It will be rescheduled for a future date.

**Speaker: ****Dylan Thurston at Indiana University Bloomington, Professor of Mathematics**

Title: The wilds of the Mandelbrot set

Abstract: What is the simplest model of how a population evolves under time? And what does that have to do with complex numbers? We will investigate the mysterious depths of the Mandelbrot set, which controls the behavior of a wide variety of different systems. We will explore combinatorial models, and how you can use them to navigate your way around the set. To illustrate this, I quite like the image of the MandelMap. In particular, I'm going to start with the relation between the logistic map and the Mandelbrot set, laid out quite nicely in one part of the Logistic-Mandel poster (image pending).

Link to the talk is at 4:00 p.m. at https://cornell.zoom.us/j/94088278451?pwd=UElBM1hqYVZKakxjTGZ3WTY1RllYZz09

After the talk please join us in Gather.town at around 5:15 p.m. Gather.town is a virtual interactive online platform where we can meet, play some virtual games, share some Q&A, and more. Here is a .pdf document with directions to help get you started and assist you in navigating Gather.town if needed.

Please note that Gather.town is not supported on Safari, nor is it supported on mobile devices (phones, tablets, etc.).

We look forward to seeing you.

If you need any accommodations or assistance with accessibility to participate in this event please contact Heather Peterson.
