Atlantic Graph Theory Seminar: Jordan Barrett, PhD Candidate, McGill University
The Atlantic Graph Theory Seminar series will take place every Wednesday from 3:30-4:30 ADT online via zoom. The talks, provided by researchers, postdocs and graduate students, will be on a variety of current topics in graph theory. If you would like to give a talk or attend, please email one of the organizers (Jason Brown and Danielle Cox).

AARMS COVID-19 Seminar: Sanjeev Seahra (UNB)
COVID-19 modelling in New Brunswick and elsewhere We present a simple differential equation based model of the COVID-19 pandemic that allows for time-evolving social distancing. We apply the model to the first 80 days of the pandemic in 24 different jurisdictions to quantify the effectiveness of government lockdowns in March 2020. Using Bayesian methods, we then estimate model parameters relevant to the current outbreak in New Brunswick. This is a virtual zoom seminar. If you would like to attend, please email…

The localization game played on graph Graph searching investigates combinatorial models for the detection or neutralization of an adversary’s activity on a network. One such model is the localization game, where pursuers use distance probes to capture an invisible evader. We present new results on the localization number of a graph, which is the minimum number of pursuers needed to capture the evader. We survey what is known and unknown for the localization number, discuss connections with the chromatic number,…

Covid-19 management in Newfoundland and Labrador Atlantic Canada and the territories have experienced a qualitatively different COVID-19 epidemic than the other Canadian provinces. The question is, do these differences suggest different best approaches to public health policy or they are just the consequence of geographic/demographic conditions? When infection prevalence is low, imported infections are not only a large fraction of all infections, but a major trigger of outbreaks. This also posses questions about the merits of travel restrictions as well…

Marginally Outer Trapped (Open) Surfaces in 4+1 Dimensional Schwarzschild In the case of binary black hole mergers, the surface of most obvious interest, the Event Horizon, is often computationally difficult to locate. Instead, it is useful to turn to quasi-local characterizations of black hole boundaries, such as Marginally Outer Trapped Surfaces (MOTS), which are defined for a single time slice of the spacetime, and the outer-most of which is the apparent horizon. In this talk, I will describe ongoing work…

Permutations of finite subsets of R^2 generated by Euclidean distances Given a finite set of points S = {P1, P2, . . . , Pn} and a vantage point V, generate an ordering of the points of S by measuring the Euclidean distance from V to each of the points of S, ordering them from nearest to farthest. As the vantage point moves around the plane, different orderings will be generated. We are interested in the maximum, minimum, and intermediate…

AARMS COVID-19 Seminar: James Watmough (UNB)
Case importation and community spread: post-pandemic control of the spread of SARS-CoV-2 in low density populations It has been just over one year and 100 million cases since we first heard of a novel coronavirus with pandemic potential. We are now all far too familiar with epidemic curves and would very much like to see the tail of this one. In this talk, I will review the simple mathematical models for the transition from pandemic to endemic and what they…
