In this talk, we will study the mean field limit of weakly interacting diffusions for confining and interaction potentials that are not necessarily convex. We explore the relationship between the large N limit of the constant in the logarithmic...

In his seminal work on modular curves and the Eisenstein ideal, Mazur studied the existence of congruences between certain Eisenstein series and newforms, proving that Eisenstein ideals associated to weight 2 cusp forms of prime level are locally...

The Coast Combinatorics Conference Series began in 1999. In most years there has been a meeting on the Canadian west coast in February or March, featuring a collegial, collaborative, workshop-style atmosphere and a diverse collection of talks on...

The defining property of fine moduli stacks (of curves) is that they have 'universal families' which translates the study of a family of (curves) as the study of morphisms to moduli stacks. I will explain this idea using Hom_{n}(P^1, Mbar_{1,1}) the...

Sharpness is a generic assumption in continuous optimization that bounds the distance to the set of minimizers in terms of the suboptimality in the objective function. It leads to the acceleration of first-order optimization methods via so-called...

As the underlying configuration behind many elegant finite structures, partial difference sets have been intensively studied in design theory, finite geometry, coding theory, and graph theory. In the first part of this talk, I will showcase that...

We will characterize members that maximize/minimize the second largest adjacency eigenvalue in certain families of trees. Joint work with H. Kumar, B. Mohar and S. Pragada.

Although my talk is arguably about machine-learning, I will use mostly ideas and language from mathematical modelling and numerical analysis. I will introduce a natural geometric learning framework, the atomic cluster expansion (ACE), which focuses...

In this talk we consider the injective chromatic index and the oriented chromatic number of graphs with bounded Euler genus. In particular, we present our proofs of a tight (up to the choice of little o(1)) bound on the injective chromatic index in...

In order to classify certain small generalized hexagons, Cohen and Tits proved that the d-dimensional hypercube has a unique 2-fold cover with no 4-cycles. I will discuss some reasons I find these covers interesting, including a close connection to...
