Atlantic Graph Theory Seminar
Time: 3:30 pm, Atlantic time, (4:00 pm NST) Wednesday, Feb. 12 Speaker: Robert Bailey, Memorial University Title: Computer constructions of distance-regular graphs with primitive automorphism groups Abstract: A graph is distance-regular if, for each vertex $v$ and each vertex $w$ at distance $i$ from $v$, the number of neighbours of $w$ at distances $i-1$, $i$ or $i+1$ from $v$ depends only on $i$, and not on the choice of $v$ or $w$. These are highly-structured graphs with interesting structural and…

Girls STEM Up is collectively 28 women students based in Fredericton, NB, who are passionate about bridging the gap of gender inequity in STEM fields, focusing on intersectionality. Founded in 2019, with the goal of sparking necessary discussions and changing the perception of women in STEM. We have since expanded to include 60+ general members, high school ambassadors, and volunteers. Our experiences as underrepresented individuals in STEM have brought us together to promote diversity, inclusion, and equity in these fields…

The Integration Competition is a fun, head-to-head competition among first-year calculus students to solve integrals, with the winners of each matchup progressing to further rounds until a winner emerges. Participants challenge themselves to solve integral problems on-the-spot, and in addition to generating interest and excitement in mastering this mathematical skill, the event is used to promote mathematics more broadly to potential majors.

Speaker: Karen Meagher, University of Regina 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…

Time: 3:30 pm, Atlantic time, (2:30 pm EST) Wednesday, Mar. 12 Speaker: Ron Gould, Emory University 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…

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…

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…

The Burning Number of Large Caterpillars Danielle Cox, Mount Saint Vincent University Abstract: In this talk we will look at the history of the graph burning conjecture and the state of the art. We will also prove the conjecture for sufficiently large p-caterpillars. This is joint work with Kerry Ojakian (CUNY) and Margaret-Ellen Messinger (Mt Allison).
