Dalhousie-AARMS AAMP Seminar: John Toth (McGill University)
Zoom seminarTitle: Pointwise bounds for joint eigenfunctions of quantum completely integrable (QCI) systems Abstract: I will discuss some recent results on improvements in supremum bounds for joint eigenfunctions of QCI systems together with sharp exponential decay estimates away from the projections

Atlantic Graph Theory Seminar: David Pike (Memorial)
Zoom seminarPerfect 1-Factorisations A matching in a graph $G$ is a subset $M \subseteq E(G)$ of the edge set of $G$ such that no two edges of $M$ share a vertex. A 1-factor of a graph $G$ is a matching $F$

Dalhousie-AARMS AAMP Seminar: Julie Rowlett (Chalmers, Sweden)
Zoom seminarDecisions and Disease Do you usually get a flu shot every year? Do you usually take preventive measures to avoid contracting sexually transmitted infections? It is reasonable to expect that while many people may answer `no‘ to the first question,

Atlantic Graph Theory Seminar: Dr. Ben Cameron (University of Guelph)
Zoom seminarTitle: Families of graphs containing only finitely many vertex-critical graphs. In this talk, motivated by algorithmic aspects of graph colouring, we will consider the problem of classifying vertex-critical graphs in families of graphs. We will complete a dichotomy theorem for

Dalhousie-AARMS AAMP Seminar: Hari Kunduri (Memorial University)
Zoom seminarTitle: Geometric inequalities for axisymmetric black holes Abstract: In general relativity, isolated, dynamical black holes arise from asymptotically flat initial data for the Einstein equations. Such data are characterized by invariants such as the ADM mass and angular momentum. When angular

Atlantic GR Seminar: Turkuler Durgut (MUN)
Zoom seminarAsymptotically Anti-de Sitter Gravitational Solitons In this talk, I will consider the stability of asymptotically anti-de Sitter gravitational solitons. These are globally stationary, asymptotically (globally) AdS spacetimes with positive energy but without horizons. I will introduce my ongoing project investigating

Atlantic Graph Theory Seminar: Iain Beaton (PhD Candidate, Dalhousie University)
Zoom seminarThe Average Order of Dominating Sets of a Graph This talk focuses on the average order of dominating sets of a graph. We find the extremal graphs for the maximum and minimum value over all graphs on n vertices, while

Dalhousie-AARMS AAMP Seminar: Jean-Pierre Garbardo (McMaster University)
Zoom seminarTitle: Factorization of positive definite functions through convolution and the Turàn problem Abstract: If $G$ is a finite abelian group, we call a subset $S\subset G$ symmetric if $0\in G$ and $-x\in S$ whenever $x\in S$. We also let $S^*=(G\setminus

Atlantic Graph Theory Seminar: Dr Andrea Burgess (University of New Brunswick, Saint John)
Zoom seminarEquitably colourable cycle decompositions A $c$-colouring of a decomposition of a graph $G$ is an assignment of $c$ colours to the vertices of $G$. A colouring is equitable if each colour is represented (as closely as possible) an equal number

Dalhousie-AARMS AAMP Seminar: Reem Yassawi (Open University, London)
Zoom seminarTitle: Some tame or wild Cantor dynamical systems Abstract: A topological dynamical system is a pair $(X,T)$ where $X$ is a compact metric spaces and $T$ is a group or semigroup acting continuously on $X$. One algebraic invariant of a
