Thematic Program "Mathematical Foundations of Data Science"
2025-05-05 - 2025-06-30 | Centre de Recherches Mathématiques, Montréal, Pavillon André-Aisenstadt 2920, chemin de la Tour, bureau 5357, Montréal, Québec, H3T 1J4, Canada
The rise of big data has caused a tectonic shift in the field of data science, opening up new possibilities but also coming with new challenges, such as the curse of dimensionality. These changes have revived old ideas and inspired new approaches in many areas of applied mathematics. Some of the most fascinating and impactful developments are now taking place at the interface of optimization, probability theory, numerical analysis, approximation theory and their interplay with machine and statistical learning. Motivated by this recent transformations, our thematic program will bring together established researchers as well as students and postdocs to learn about the most recent trends in the field, share emerging ideas and foster new collaborations. The main activities of the program will be five workshops and one spring school. The program will also host several long-term visitors and two Aisenstadt Chairs that will deliver distinguished lectures.

Numerical modelling of layered complex fluids
2025-05-05 - 2025-05-09 | Halifax, Halifax, Nova Scotia, Canada
Layered complex fluids, such as smectic liquid crystals, possess remarkable properties because of the geometric and topological consequences of layering: external forces lead to deformations of the fluid that are incompatible with the layering, leading to geometric frustration and the spontaneous assembly of a wide variety of textures. There has been a recent explosion of interest in exploiting the ability of smectics, as a paradigmatic example of a layered fluid, to repeatedly self-assemble over device length-scales. As we advance our theoretical and experimental understanding of these fluids, we may be able to develop highly attractive metamaterials for use as lenses, lithographic templates, or in other devices. However, the very complicated structures that emerge in these systems have proven to be extremely challenging to model computationally. We will bring together experts in experimentation, theory, and simulation, to focus on understanding the structures of these materials.

Title: Liminal burning the hypercube

Abstract: Liminal burning generalizes both the burning and cooling processes in graphs. In $k$-liminal burning, a Saboteur reveals $k$-sets of vertices in each round, and the Arsonist must choose sources only within these sets. The result is a two-player game with the corresponding optimization parameter $b_k$ called the $k$-liminal burning number. For $k = |V (G)|$, liminal burning is identical to burning, and for $k = 1$, liminal burning is identical to cooling. Here, we study the behavior of $k$-liminal burning on the hypercube graph $Q_n$ and note that finding the $k$-liminal burning number of $Q_n$ is strongly related to finding an appropriate Sperner family—a family of sets where no element is a proper subset of another. We introduce a variant of these Sperner families that, alongside other methods, allows us to establish bounds on $b_k(Q_n)$ for various values of $k$. We also determine the exact cooling number of the $n$-dimensional hypercube to be $n.$

Title: Smoothed analysis for graph isomorphism
Abstract: I’ll describe a simple algorithm which shows the following: Given any graph G, add or remove edges uniformly at random with probability 100/v(G) to create a graph G’. We can test in polynomial time if G’ is isomorphic to any other graph H. In other words, graph isomorphism is in P if you add a little bit of randomness to the instance.

Title: Cameron’s conjecture on random Latin squares

Abstract: A conjecture of Cameron states that the distribution of the number of odd rows in an n x n uniformly random Latin square is approximately binomial with n trials and success probability 1/2. We prove this conjecture in several different senses, including total variation convergence, a local central limit theorem, and a large deviation principle. In fact, we prove a generalisation for the joint distribution of the number of odd rows, odd columns and odd symbols, showing they behave roughly as independent binomials. Along the way, we introduce several general techniques for the study of random Latin squares, including a new re-randomisation technique via “stable intercalate switchings”, and a new approximation theorem comparing random Latin squares with a certain independent model.
This is joint work with Matthew Kwan and Mehtaab Sawhney.

Title: On the eigenvalues of the graphs D(5, q)

Abstract: In 1995, Lazebnik and Ustimenko introduced the family of q-regular graphs D(k, q), which is defined for any positive integer k and prime power q. The connected components of the graph D(k, q) have provided the bestknown general lower bound on the size of a graph for any given order and girth to this day. Furthermore, Ustimenko conjectured that the second largest eigenvalue of D(k, q) is always less than or equal to 2√q, indicating that the graphs D(k, q) are almost Ramanujan graphs. In this talk, we will discuss some recent progress on this conjecture. This includes the result that the second largest eigenvalue of D(5, q) is less than or equal to 2√q when q is an odd prime power.

Session on Combinatorial Design Theory at the 2025 CMS Winter Meeting
2025-12-05 - 2025-12-08 | Toronto, Toronto, Ontario, Canada
In the 18th century, several seemingly innocuous scheduling problems were proposed, often in the form of a puzzle. These problems were ultimately solved using tools and theoretical approaches that now lie in what is known as combinatorial design theory. Since then, this area of mathematics has seen tremendous growth in the diversity of designs, constructions, and applications that it encompasses. The purpose of this session is to showcase recent results in topics such as classical designs, cycle systems, graph decompositions, Latin squares and other aspects of design theory.
