Stable matching mechanisms are ubiquitous in theory and in practice, with centralized mechanisms used to match students to schools or medical residents to hospitals. It is known that imbalance in the number of agents on either side of a random...

Let $A$ be an abelian surface. We investigate curves in a linear system on the dual abelian surface $\hat{A}$. There is an isomorphism of moduli spaces due to Yoshioka between the space $K_3(A)$ parametrizing 0-dimensional length-4 subschemes on $A$...

Back in 1848, in a German chess magazine, Max Bezzel asked how many ways there are to place 8 queens on a chessboard so that no two queens can attack one another. This question caught the attention of many, including Gauss, and was subsequently...

The Inverse Eigenvalue Problem for Graphs (IEP-G) concerns determining all possible spectra of matrices in S(G), the set of real symmetric matrices described by a graph. Specific subproblems involve studying the maximum nullity or minimum rank, the...

Marginal Expected Shortfall (MES) has become a central measure for assessing systemic risk. In this talk, I trace MES back to its theoretical roots in weighted risk-capital allocation rules and show that, perhaps counterintuitively, MES can be...

Building on last week's talk, I discuss Locally Cartesian Closed Categories (LCCCs) , in which every slice category is Cartesian Closed. I describe how these categories serve model quantifiers in logic, as well as modelling type dependencies in a way...

Enumerating vector bundles of a fixed rank over a given manifold is a classical question in topology. While vector bundles are stably computable via K-theory, in the unstable range they become much harder to detect. In this talk, we will demonstrate...

This Alternative Math Education event will present fun methods of teaching math and computer science concepts to children (and adults!) using games and art. Lots of hands-on activities! Including: A Sorting Network An Impossible Balancing Act Bubbles...

Stay tuned for event details!

Juvan, Malnič and Mohar [J. Combin. Theory Ser. B 68 (1996), 7-22] proved that for every surface S and every integer k, there exists N(S,k) such that any set of simple closed curves on the surface S, where any two are non-homotopic and intersect at...
