SUMMARY:Math Kitchen Party: organized by Branimir Cacic (UNB Fredericton)
DESCRIPTION:The Oberwolfach Problem\nAndrea Burgess (UNB Saint John)\nThe Oberwolfach Problem was posed by Ringel as a seating problem:  people attend a conference in Oberwolfach\, where the dining room has round tables of sizes  (with ). Is it possible to devise a seating plan over successive dinners in which each person sits next to each other person exactly once? \nIn graph-theoretical terms\, the Oberwolfach Problem asks whether\, given a 2-factor  of order \, the complete graph  can be decomposed into copies of . In this talk\, we present solutions of the Oberwolfach Problem obtained via graceful labellings. This is joint work with Peter Danziger (Ryerson) and Tommaso Traetta (Brescia). \nThe Unitary Birkhoff-von Neumann theorem\nStijn De Baerdemacker (UNB Fredericton)\nBirkhoff has shown that the doubly stochastic matrices can be written as a weighted sum over the permutation matrices of the same dimension. I will show that a similar theorem holds for unitary matrices with equal linesum\, and talk about applications in quantum computing. \nMusical Guests\n\nTBA\n\nThis is a virtual zoom meeting.  If you would like to attend\, please email the organizers for connection details. \n[more information about the Math Kitchen Party summer talk series]

SUMMARY:AARMS COVID-19 Seminar: Matthew Betti (Mount Allison)* and Jane Heffernan (York)
DESCRIPTION:Scenario-based modeling of healthcare demand and PPE usage during the COVID-19 pandemic\nOne 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 us to narrow possible trajectories which can then be fed into the healthcare demand and PPE modules. We show results for possible outcomes from each of our three modules and from our fitting techniques. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.

SUMMARY:Math Kitchen Party: organized by Daniele Turchetti (Dalhousie)
DESCRIPTION:Number Theory in Quantum Mechanics\nSuresh Eswarathasan (Dalhousie | 8:00-8:20)\nIn 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. \nGetting Back to Your Roots\nJason Brown (Dalhousie | 8:40-9:00)\nPolynomials arise in various combinatorial settings\, and their roots are of interest for both applied and theoretical reasons. In this talk I’ll provide a few examples\, and show how exploring the nature and location of the roots can connect us back to giants of the past\, such as Newton\, Gauss\, Hermite and Julia. \nMusical Interlude\n\nDorette Pronk (Dalhousie)\n\nThis is a virtual zoom meeting.  If you would like to attend\, please email the organizers for connection details. \n[more information about the Math Kitchen Party summer talk series]

SUMMARY:Quantum Gravity 2020
DESCRIPTION: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. \nA second goal is to work towards combining the insights gained in the various approaches. In its overall goal as well as the format\, this conference will differ from more specialized meetings that focus on specific quantum-gravity approaches. \nWe hope that this inaugural conference “Quantum Gravity“ can make a contribution to bridging the gaps between quantum gravity approaches\, and bring the entire community together for a constructive and fruitful exchange.

SUMMARY:CMS COVID-19 Research and Education Meeting (CCREM)
DESCRIPTION: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. \nThe session will cover NSERC’s response to the COVID-19 pandemic including new funding opportunities for researchers\, changes in policies for NSERC Discovery grants and scholarship and fellowship programs. NSERC staff will also be answering questions regarding the coming Discovery grant competition.

SUMMARY:AARMS COVID-19 Seminar:  Sana Jahedi (UNB) and James A. Yorke (Maryland)
DESCRIPTION:When the best pandemic models are the simplest\nAs a pandemic of coronavirus spreads across the globe\, people debate policies to mitigate its severity. \nMany 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. \nWe 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 population. Such models can be understood by a broad audience\, and thus can be helpful in explaining the policy decisions to the public. They can be used to evaluate outcomes of different policy strategies. However\, simple models have a disadvantage when dealing with inhomogeneous populations. \nTo augment the power of a simple model to evaluate complicated situations\, we add what we call “satellite’’ equations that do not change the original model. \nTo compare simple models with complex models\, we introduce our “slightly complex’’ Model J. We find the conclusions of simple and complex models can be quite similar. But\, for each added complexity\, a modeler may have to choose additional parameter values for which there is often little rationale but that can have a big impact on predictions. Our simulations suggest that the added complexity offers little predictive advantage. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.

SUMMARY:Math Kitchen Party: organized by Danielle Cox (Mount Saint Vincent)
DESCRIPTION:Modelling correlated count data-can I delete the zeroes?\nGary Sneddon (Mount Saint Vincent)\nCorrelated 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). \nThe Shooter’s Hill Decorative Tiles: Combinatorics as Art\nKaryn McLellan (Mount Saint Vincent)\nThis talk will explore some of the art and mathematics inspired by a mistakenly (?) placed stone tile on a terraced house in London. A set of 70 Truchet-type tiles are the building blocks for various art pieces\, including an inkle loom weaving. In particular\, we are interested in whether or not we can weave an overlapping strip containing all 70 tiles exactly once\, and if so\, how many such strips exist. Other combinatorial properties of the tiles are examined as well. Joint work with Eva Knoll(UQAM) and Danielle Cox (MSVU). \nMusical Guests\n\nSean & Tessa Sneddon\n\nThis is a virtual zoom meeting.  If you would like to attend\, please email the organizers for connection details. \n[more information about the Math Kitchen Party summer talk series]

SUMMARY:Atlantic GR Seminar: Sharmila Gunasekaran Gnanam (MUN) and Robert Santacruz (UNB)
DESCRIPTION:Slow decay of waves in gravitational solitons\nSharmila Gunasekaran Gnanam\nMemorial University of Newfoundland\nGravitational solitons are globally stationary horizonless asymptotically flat spacetimes. In this talk\, I will describe the methodology used to prove that massless scalar waves in a particular family of soliton spacetimes decay very slowly. The proof involves the construction of quasimodes which are approximate solutions to the wave equation. This slow decay can be attributed to the stable trapping of null geodesics and is suggestive of instability at the nonlinear level. This is joint work with Hari Kunduri. \nQuantizing gravity is not that hard if you know how: An undergraduate guide to black holes\nRobert Santacruz\nUniversity of New Brunswick\nIt is expected that singularities appearing in GR are to be resolved in a theory of Quantum Gravity. In the context of Loop Quantum Gravity\, the Big Bang singularity is replaced by a bounce and so one would assume that this can be translated into Black Holes. In this talk I will explain you how to find an effective model for Schwarzschild black hole by using Loop Quantum Cosmology techniques and\, the best part is\, you only need Hamiltonian Mechanics!! \nThe Atlantic General Relativity 2020 online postdoc/student seminar series is in the tradition of the annual AGR meetings\, providing a forum not only for students and postdocs to present their research and make professional contacts but also to facilitate connections and collaborations between all Atlantic Canadian relativists. The series is student-organized and includes all areas of classical and quantum gravity. Talks will occur on the last Wednesday of every month\, with each session consisting of two 30 minute talks. If you would like to attend\, please email the organizers for connection details.
