Past Events

The challenge of solving energy distribution grid planning problems, including operation and expansion planning, stems from their combinatorial nature and the vast solution space. Several models and techniques have been proposed in the literature to...

The classical McKay correspondence shows that there is a bijection between irreducible representations of finite subgroups $G$ of $\mathrm{SL}(2,\mathbb{C})$ and the exceptional divisors of the minimal resolution of the singularity $\mathbb{C}^2/G$...

In 1966, Tate proposed the Artin–Tate conjectures, which expresses special values of zeta function associated to surfaces over finite fields. Conditional on the Tate conjecture, Milne–Ramachandran formulated and proved similar conjectures for smooth...

A classical problem in combinatorial geometry, posed by Erdős in 1946, asks to determine the maximum number of unit segments in a set of n points in the plane. Since then a great variety of extremal problems in finite planar point sets have been...

We generalize a result about the face numbers of polytopes to the realm of CW spheres. Let X be a CW sphere such that: X is strongly regular. (The intersection of any two faces is a face.) X is shellable. (We can build X, facet by facet, so that each...

This alternative math education event will present fun activities to explore math and computer science concepts to children (and adults!) using games and art! Lots of hands-on activities including: Sorting network An impossible balancing act...

An highly active research area is concerned with finding conditions on sparse sets that ensure the existence of many geometric patterns. I will present some results in this direction connecting Newhouse thickness and its generalizations to higher...

We will review how to do homotopy theory with model categories. As motivation for infinity-categories, we will discuss the benefits and drawbacks of working with model categories.

Many viruses evolve fast enough to accumulate significant genetic diversity over the course of an outbreak, allowing us to build trees that represent the evolutionary history of virus lineages. Phylodynamic models allow us to infer the...

I am going to discuss various results on moments of symmetric square L-functions and some of their applications. I will mainly focus on a recent result of R. Khan and M. Young and our improvement of it. Khan and Young proved a mean Lindelöf estimate...
