In 1959, Farahat and Higman showed a remarkable property about the symmetric group: the structure constants for the center of the group algebra Sn depend polynomially on n and that there exists an infinite-dimensional algebra, which we call the...

It is conjectured that there is no projective plane of order 12. Balanced splittable Hadamard matrices were introduced in 2018. In 2023, it was shown that a projective plane of order 12 is equivalent to a balanced multi-splittable Hadamard matrix of...

Evolutionary game theory is a discipline devoted to studying populations of individuals that are subject to evolutionary pressures, and whose success generally depends on the composition of the population. In biological contexts, individuals could be...

In Manak's talk, we learned what a deformation functor is. We will explore this notion more in depth and look at some examples. Deformation functors allow us to make the idea of a "formal moduli problem" more precise. Time permitting, we will discuss...

The Association of Women in Mathematics Student Chapter (AWMSC) is hosting a talk by Dr. Gerda de Vries titled "Hidden Figures: Eminent Women in Applied Mathematics" on January 23rd (TODAY!) from 4-5PM in CAB 457.

Let A and B be compact sets in ℝd. One of the fundamental problems in geometric measure theory is to study the relations between the Hausdorff dimensions of A, B, and A∩f(B), where f runs through a set of transformations. This type of question has...

Random band matrices provide a simple model for studying the metal-insulator transition of random operators, the prominent example of which is the Anderson model. According to the famous sqrt(N) conjecture, N x N random matrices with non-zero entries...

I will talk about the `minimal spanning arborescence', a directed version of the Minimal spanning tree. I will explain how this naturally leads to a new type of stochastic process which we call `loop contracting random walk'. I will show how this can...

Topological insulators are novel materials which are on the one hand insulators in their bulk, yet on the other hand excellent conductors along their edge. This distinguished property, and many more, are explained via the rich topological structure...

In this talk, we will discuss the classical problem, known as Falconer's distance problem, of quantifying the minimum amount of pairwise distances associated with a given Borel set in Euclidean space. For the last 25 years, methods in harmonic...
