AARMS CRG conference on Computational Aspects in Finance and Actuarial Sciences
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…

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…

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…

Number Theory in Quantum Mechanics Suresh Eswarathasan (Dalhousie | 8:00-8:20) In this lecture, I will discuss some concrete connections between two seemingly disparate fields: number theory and quantum mechanics. The first 10 minutes will be spent giving some “standard” facts in these disciplines before spending the last 10 minutes on the implications of the Sum of Two Squares Theorem (or rather, its refinements) on certain quantum waves. Getting Back to Your Roots Jason Brown (Dalhousie | 8:40-9:00) Polynomials arise in…

The conference “Quantum Gravity 2020“ has a deliberately broad scope. We aim to include participants from all current approaches to quantum gravity, as well as researchers working on the phenomenology of quantum gravity. The main goal of the meeting is to assess the progress made and to constructively and openly discuss open questions in our understanding of quantum gravity. A second goal is to work towards combining the insights gained in the various approaches. In its overall goal as well…

The CMS had to postpone the 2020 CMS Summer Meeting planned for this June due to the COVID-19 pandemic. Since we cannot hold a meeting in person, the CMS still wants to provide a virtual platform for mathematicians to come together and learn during this difficult time. We feel that a meeting focused on the changes caused by COVID-19 to the way we plan, teach and do research would be of great benefit to the Canadian mathematical community. The session…

When the best pandemic models are the simplest As a pandemic of coronavirus spreads across the globe, people debate policies to mitigate its severity. Many complex, highly detailed models have been developed to help policy setters make better decisions. However, the basis of these models is unlikely to be understood by non-experts. We describe the advantages of simple models for covid-19. We say a model is “simple’’ if its only parameter is the rate of contact between people in the…

Modelling correlated count data-can I delete the zeroes? Gary Sneddon (Mount Saint Vincent) Correlated count data with excess zeroes arise in a number of applications. We will discuss 3 motivating examples, and some approaches to modelling these type of data. Covid-19 may be mentioned, so be prepared. This is joint work with Tariqul Hasan and Renjun Ma of UNB (Fredericton). The Shooter’s Hill Decorative Tiles: Combinatorics as Art Karyn McLellan (Mount Saint Vincent) This talk will explore some of the…
