## 2018-2019 J.C. Eaves Lecture

**2018-19 J.C. Eaves Lecture**

Title: Understanding Symplectic Geometry through Polytopes and Lattice Points

Abstract: Topology is often called ``rubber sheet geometry" and is described as ``floppy" while geometry is more ``rigid". Symplectic geometry, the natural geometry of classical mechanics, is floppier than Riemannian geometry but more rigid than topology. I will give an overview of this floppy/rigid spectrum. We will then explore how the geometry and topology of symmetries in this context relate to properties of polytopes, motivated by many pictures and examples. I will conclude with how some of my recent work, joint with Daniel Cristofaro-Gardiner, Alessia Mandini and Ana Rita Pires, comes to feature continued factions, counting lattice points, and the Philadelphia subway system.

The lecture is supported by the Dr. J.C. Eaves Undergraduate Excellence in Mathematics Endowment Fund.

About the J.C. Eaves Speakers SeriesThe J.C. Eaves Undergraduate Excellence in Mathematics Endowment Fund brings speakers to campus to participate in the undergraduate mathematics program. The Fund is supported by a generous gift from James C. Eaves, Jr. and Mary Eaves, the son and daughter-in-law of J.C. Eaves. J.C. Eaves was a faculty member in the Department of Mathematics and Astronomy at the University of Kentucky and served as Chair of the Department from 1953 to 1963.

The previous speakers in the J.C. Eaves Speakers Series are:

- Francis Su, Harvey Mudd College, 2017-18
- Ken Ono, Emory University, 2016-17
- Mihai Stoicu, Williams College, 2015-16

## A&S Math Student Receives Prestigious National Scholarship

By Madison Dyment

A national scholarship can go a long way, even when the recipient is a senior. Just ask UK senior, Claire Barrera, the latest recipient of the Trjitzinsky Scholarship, one of the American Mathematical Society’s (AMS) coveted awards.

Rounding out her final year as a math major and economics minor, Barrera pins her scholarly path on her upbringing.

## From Flapping Birds to Telescopes: The Modern Science of Origami

Origami artist and scientist Robert Lang will visit the University of Kentucky on Monday and Tuesday, 22-23 October 2018 to give a public lecture and hold several workshops for students. The lecture will be of general interest. Space is limited at the workshops and we ask students to register at the links below.
