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

AARMS COVID-19 Seminar: Shannon LeBlanc (Dept of Health NB)
Zoom seminarImportation Risk under the Northern Lights To understand the risk that an infectious traveler from other Canadian provinces and territories will enter the Northwest Territories the Government of the Northwest Territories has fitted jurisdictional reported COVID-19 transmission data to a

Atlantic Graph Theory Seminar: Kyle MacKeigan (PhD Candidate, Dalhousie University)
Zoom seminarOrthogonal Colourings of Graphs Two colourings of a graph are orthogonal if they have the property that when two vertices receive the same colour in one colouring, then those vertices receive distinct colours in the other colouring. In this talk,

Atlantic GR Seminar: Jinzhao Wang (ETH Zurich) and Saikat Mondal (MUN)
Zoom seminarOuter entropy equals Bartnik-Bray inner mass, and the gravitational ant conjecture Jinzhao Wang (ETH Zurich) Entropy and energy are found to be closely tied on our quest for quantum gravity. We point out an interesting connection between the recently proposed

Atlantic Graph Theory Seminar: Dr Jared Howell (Memorial University of Newfoundland, Grenfell Campus)
Zoom seminarGracefully labelling windmills using Skolem-like sequences To gracefully label a graph G, assign each vertex v ∊ V(G) a distinct label l(v) from {0,1,2,...,|E(G)|}, such that {|l(u)-l(v)| : uv ∊ E(G)}={1,2,3,...,|E(G)|}. In this talk we will examine constructive techniques using
