CMS Special Session: Designs and Codes
Designs and codes are very active areas of research in combinatorics. There have been numerous breakthroughs in recent years, such as the existence proof for Steiner systems for arbitrary values of t. Research in designs, codes and their interaction includes both mathematical and algorithmic questions. Proofs encompass both constructions and probabilistic methods, and employ diverse mathematical techniques from algebra, number theory, graph theory, etc. In addition, there are numerous applications, in areas such as cryptography, in which designs and codes…

The Euler’s method and the Gillespie algorithm to simulate a stochastic SIR model (part 2) JC Loredo-Osti (MUN) The second part of this presentation will be used to talk about some example of extensions to the stochastic SIR model. We will start with adding compartments that leave the fundamental structure of the model unchanged, like the ones that add a latent class or add compartments to accommodate for metapopulations, as well as incorporating the serial-time distribution to model the infectious…

The Queer and Trans Mathematicians in Combinatorics conference (QTMC) is a first-ever event in combinatorics specifically aimed at queer and trans mathematicians. It aims to bring together and support queer and trans combinatorists. The conference promotes a supportive and active collaborative environment for the participants and aims to bring about visibility to an otherwise underrepresented invisible minority in the combinatorics community. The QTMCis heavily geared toward students, postdocs and early career mathematicians who are queer and/or trans.

Planning for Covid-19: Government’s informational needs in a time of uncertainty Mathieu Chalifoux (Government of New Brunswick) In this presentation, we will go over three questions that have recently been posed to the mathematical sciences community in Fredericton, New Brunswick as a means to better understand and plan for the incidence of COVID-19 in the coming months. Further discussion will ensue with all participants as a means to discuss what type of information is useful to governments during this ongoing…

Pokemon in the City Danny Dyer (Memorial University of Newfoundland) When playing Pokemon Go, trying to catch all the Pokemon in a big, grid like city is difficult, but can be discussed in terms of the watchman number of grid graphs. We present some bounds for these graphs, and argue that is better to play Pokemon Go on a toroidal space station. Gotta catch ‘em all! Passing the buck: a chip firing game M.E. Messenger (Mount Allison) Suppose a group…

The AARMS CRG Conference on Computational Aspects in Finance and Actuarial Sciences will be held June 19-20th, 2020 in PEI, Canada. This conference is mainly hosted by the Atlantic Association for Research in Mathematical Sciences (AARMS) collaborative research group (CRG) and the School of Mathematical and Computational Sciences (SMCS) at University of Prince Edward Island (UPEI), Canada, and is a unique venue that brings together leaders in finance, and actuarial sciences, across disciplines, and across borders, tackling very important and…

Source Sink Diffusion Danielle Cox (MSVU) We will introduce the diffusion process on graphs with the addition of sources and sinks. In particular, we will provide some results regarding the periodicity of the process. This is joint work with Todd Mullen (Dalhousie University), Shayne Breen (MSVU), Emily Wright (MSVU) and Jesse Preston (MSVU). More Fun with the Sierpinski Relatives Tara Taylor (StFX) The Sierpinski gasket is a well-known fractal that can be described as the attractor of an iterated function…

Math Kitchen Party: organized by Branimir Cacic (UNB Fredericton)
The Oberwolfach Problem Andrea Burgess (UNB Saint John) The Oberwolfach Problem was posed by Ringel as a seating problem: $n$ people attend a conference in Oberwolfach, where the dining room has round tables of sizes $k_1, k_2, \ldots, k_t$ (with $k_1 + \cdots + k_t = n$). Is it possible to devise a seating plan over successive dinners in which each person sits next to each other person exactly once? In graph-theoretical terms, the Oberwolfach Problem asks whether, given a…

Scenario-based modeling of healthcare demand and PPE usage during the COVID-19 pandemic One of the big risks during the current pandemic is stress and overburdening of the healthcare system, and a possible scarcity of resources. We will present a three module model that projects possible epidemic outcomes and subsequently measures healthcare demand and PPE usage for different jurisdictions across Canada. We present as well a simple model which we fit to current cases with some novel sampling techniques which allows…
