Julia Robinson and Hilbert's Tenth Problem

(UIUC Math)

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.

How to Tile Your Bathroom: An Extremely Impractical Guide from a Mathematician

Prof. Sean English   [email] (UIUC Math)

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.

The Arithmetic of Quadratic Fields

Patrick Allen (UIUC Math)

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.

IGL Fall 2020 Info Session

Alexi Taylor Block Gorman   [email] (UIUC Math)

Abstract: We will be joined by Alexi Block Gorman! She is a third-year PhD student here in the math program, and also the Illinois Geometry Lab's (IGL's) current research manager. She'll be joining us to to talk about applying to the IGL, as well as answering any questions you might have about how the IGL will be run during the next semester. If you're thinking about applying, or even just wondering what exactly the IGL is, this will be an important meeting to join! For a meeting link, please email drthoma2@illinois.edu.
