The Undergraduate Friday Seminar (UFS) is a weekly event aimed at showing undergraduate mathematics students a taste of what they can experience from the professional world of mathematics research. Every Friday, we sit down with a different speaker as they tell us all about the interesting work they do and some of the neat results from their field!
Unlike many seminars, we make it a point to have material presented at a level that even the youngest of mathematicians can grasp. We also include undergraduates as our presenters; all of which is done in an effort to cultivate a generation of mathematicians who can accurately and engagingly present their work and interests to others.

If you have any questions about these weekly seminars, or wish to give a presentation during the semester, feel free to email us at email@example.com. (See below for a list of previous topics and presentations.)
Previous Seminars (Spring 2020)
Speaker: Patrick Allen, assistant professor, member of the Number Theory Group @ Illinois
Title: The Arithmetic of Quadratic Fields
Abstract: It is often said that the prime numbers are the building blocks of the integers, the precise statement of which is the fundamental theorem of arithmetic: any integer greater than one can be factored uniquely as a product of prime numbers. What if we move beyond the integers? The simplest cases to consider are the analogues of the integers in what are called quadratic fields, which are number systems obtained from adding to the rational numbers the square root of some fixed integer. Whether or not these quadratic integers satisfy the analogue of the fundamental theorem of arithmetic turns out to be very subtle and both what is known and what is not known are rather surprising.
Speaker: Kyle Begovich, Mathematics and Computer Science Senior @ Illinois
Title: Python Workshop
Abstract: Kyle will be working at Google as a software engineer at the end of this semester. He'll be running a workshop on Python through Project Euler, a great way to get a jumpstart on learning some of the basics of solving problems through coding. No prior coding experience is needed for this workshop! Project Euler is an online platform for students in any discipline to work on “challenging mathematical/computer programming problems that will require more than just mathematical insights to solve”. In this time of remote work, a platform that is online and well-suited to developing problem-solving techniques can provide a good outlet for learning new skills, developing your analytic senses, and interacting with a community of mathematical thinkers. This seminar will help you set up an environment, discuss common approaches to work on these problems, and walk through some early problems to get you started.
Speaker: Sean English, J.L. Doob Research Assistant Professor
Title: How to Tile Your Bathroom: An Extremely Impractical Guide from a Mathematician
Abstract: Tilings have been considered by mathematicians for centuries and by artists for millennia. The main question for tiling problems involves asking if a small number of shapes can be used to cover an entire geometric region without gaps or overlaps. We will briefly talk about some of the history behind tilings, then we will explore many interesting different directions these sorts of problems can take. We will explore some questions as simple as "which regular polygons can tile the plane?" to questions as obscure as "do chickens give rise to a periodic tiling?" Disclaimer: Unless your bathroom is infinite in size, follows spherical or hyperbolic geometry, or has a floor that is more than two dimensional, this talk may not actually be helpful for tiling your bathroom
Title: Julia Robinson and Hilbert's Tenth Problem (film)
Abstract: Julia Robinson was the first woman elected to the mathematical section of the National Academy of Sciences, and the first woman to become president of the American Mathematical Society. While tracing Robinson's contribution to the solution of Hilbert's tenth problem, the film illuminates how her work led to an unusual friendship between Russian and American colleagues at the height of the Cold War.
Speaker: Raghavendra Bhat, Freshman Mathematics Major, UIUC
Title: Prime Number Conjectures
Abstract: Freshman math major and author (Math -- A Subtle Language of the Universe) Raghavendra Bhat will present some of his prime number conjectures, which he has presented on many platforms across the world. His talk will focus on his recent conjectures and thoughts on number theory research and math in general.
Speaker: David Altizio, University of Illinois at Urbana-Champaign
Title: A Brief Introduction to Problem Writing
Abstract: Many of the best mathematics competition problems push the boundaries of pre-calculus math in unexpected ways. While these questions fuel the popularity of contests among middle and high school students, they also make competitions seem inherently unsustainable; constructing these questions appears to be a Herculean task. In this talk, I will shed some insight into how problems are made by exploring my eight-year-long journey through problem writing. In particular, I will discuss common writing philosophies, sources of inspiration, and the stories behind some of my favorite creations.
Speaker: Robert Joseph Rennie, University of Illinois at Urbana-Champaign
Title: What Is A Mathematics?
Abstract: In this talk, I will begin with a mathematization of the process of mathematization. We will then see how category theory and type theory provide a nice general framework for constructing and comparing systems of math. This discussion will motivate, without ever mentioning topological spaces, the study of higher toposes to anyone who cares about theoretical physics (not necessarily just those who study it). This talk requires only an interest in thinking about how math works.
