Title: Derangement graphs and the intersection density of permutation groups

Abstract:
Two permutations are intersecting if they both map some $i$ to the same point, equivalently, permutations $sigma$
and $pi$ are intersecting if and only if $pi^{-1}sigma$ has a fixed point. A set of permutations is called intersecting if any two permutations in the set are intersecting. For any transitive group the stabilizer of a point is an intersecting set. The intersection density of a permutation group is the ratio of the size of the largest intersecting set in the group, to the size of the stabilizer of a point. If the intersection density of a group is 1, then the stabilizer of a point is an intersecting set of maximum size. Such groups are said to have the ErdH{o}s-Ko-Rado property.

One effective way to determine the intersection density of a group is build a graph whose vertices are the elements of the group and the edges are defined so that the cocliques (or the independent sets) in the graph are exactly the intersecting sets in the group. This graph is called the derangement graph for the group. The focus on this talk is to demonstrate several ways we can use the derangement graph to find the intersection density of a group.

An easy example of how this can be done is if the graph has a clique with the size of the degree of the group, then the group has intersection density 1. We can also use graph homomorphisms to find bounds on the intersection density. For many small groups, the derangement graph has a very simple form and the intersection density of the group can be easily found simply from the structure of the derangement graph. In a surprising number of cases, eigenvalues of the derangement graph can be found using the representation theory of the group and, using tools from algebraic graph theory, these eigenvalues can be used to bound the size of a coclique.

A Hybrid Seminar Series for University Students in Statistics or Computer Science
“Mediation Analysis of Recurrent Events”
Guest Speaker: Shenita Pramij (Memorial University)
DATE: Friday, March 7, 2025
TIME: 12:00–1:00 p.m., Atlantic time
LOCATION: Online via Zoom
This hybrid series for students in statistics and computer science programs features faculty members and students from universities in Atlantic Canada talking about their work and career paths in statistical sciences. The guest speaker for this online presentation will be Shenita Pramij.
Shenita is a PhD student in Statistics at Memorial University of Newfoundland. Her research focuses on mediation analysis, and she has broad interests in modelling complex processes with applications in healthcare and public policy. She also has extensive experience in the public sector as a compliance researcher. Her work aims to enhance decision-making in public policy and inform targeted interventions.
PRESENTATION ABSTRACT : Inferring the direct effects of exposure in recurrent event processes, while accounting for mediating factors, is crucial, yet conventional approaches face significant limitations in the presence of complex causal relationships. We introduce two methods to address these challenges. We first explore a two-stage sequential G-estimation method to estimate the controlled direct effect of a randomly assigned exposure, while accounting for potential mediators and confounders, using intensity-based models of recurrent event processes. We also introduce a novel one-stage estimation method based on the estimating equations framework, leveraging the sequential G-estimation principle. We demonstrate that both methods yield unbiased controlled direct effect estimates. The one-stage method also enables the analytical derivation of an estimator for the standard error of the direct effect estimator. We illustrate our approach using a hospital readmission dataset of colorectal cancer patients to estimate the controlled direct effect of sex differences on hospital readmission.

Title: Looking for Saturation in all Kinds of Places

Abstract:
Given a graph $H$, a graph $G$ is $H$-saturated if $G$ does not contain $H$ as a subgraph, but the addition of any missing edge to $G$ results in a graph containing $H$ as a subgraph. An $H$-saturated graph with the maximum number of edges is called an extremal graph for $H$ and for a given order $n$ we denoted this as $ext(n, H).$ This is the well-known extremal number (or Turan number) of $H$ and is a well studied notion with a deep and beautiful history.

However, the focus of this talk will be the many other saturation questions that can be asked. These include what is the minimum number of edges in an $H$-saturated graph? What sizes (i.e. $|E(G)|$), other than the minimum or maximum, also allow $H$-saturated graphs on $n$ vertices? Is it possible to order the inclusion of the missing edges so that at each stage more copies of $H$ will be included? What about saturation in other settings such as in hypergraphs, edge-colored graphs, random graphs, or within graphs other than the complete graph?

Keywords: saturation, saturation spectrum, weak saturation

The 2-burning number of a graph
Speaker: Ann Trenk, Wellesley College

Abstract:
We discuss a discrete-time model for the spread of information in a graph, motivated by the idea that people believe a story when they learn of it from two different origins. Similar to the burning number, in this problem, information spreads in rounds and a new source can appear in each round. For a graph $G$, we are interested in $b_2(G)$, the minimum number of rounds until the information has spread to all vertices of graph $G$. We are also interested in finding $t_2(G)$, the minimum number of sources necessary so that the information spreads to all vertices of $G$ in $b_2(G)$ rounds. In addition to discussing general results, we find $b_2(G)$ and $t_2(G)$ for the classes of spiders and wheels and show that their behavior differs with respect to these two parameters.

This is joint work with Catherine Jacobs (Wellesley College) and Margaret-Ellen Messinger (Mount Allison University).

Mini course "Vertex operator algebras and their representations"
2025-03-24 - 2025-03-28 | Memorial University (St. John’s Campus), St. John's, Newfoundland and Labrador, Canada
Vertex operator algebras have been a topic of interest in mathematical physics for several decades, as they constitute one possible approach to formalize physical concepts from conformal field theory. They have relations to several other areas of mathematics, most notably to the theory of finite simple groups. This specific relation lead in fact to the award of the Fields Medal to Professor Richard Borcherds at the International Congress of Mathematicians in Berlin in 1998. Professor Gannon is the author of a well-known monograph on this topic.
The minicourse will consist of five lectures of 90 minutes each. The lectures will be aimed at students, primarily at the graduate level. We hope to attract about 20 participants from Memorial University, Atlantic Canada, and other parts of Canada, and possibly some international participants.

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.
