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

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

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

Date and Time: Wednesday, October 22, 3.40 pm Atlantic time Speaker: Theodore (Teddy) Mishura, Toronto Metropolitan University 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
