SUMMARY:Dalhousie-AARMS AAMP Seminar: Michael Ward (UBC)
DESCRIPTION:Synchrony and Oscillatory Dynamics for a 2-D PDE-ODE Model of Diffusion-Sensing with Small Signaling Compartments\nWe analyze a class of cell-bulk coupled PDE-ODE models\, motivated by quorum and diffusion sensing phenomena in microbial systems\, that characterize communication between localized spatially segregated dynamically active signaling compartments or “cells” that have a permeable boundary. In this model\, the cells are disks of a common radius and they are spatially coupled through a passive extracellular bulk diffusion field with diffusivity in a bounded 2-D domain. Each cell secretes a signaling chemical into the bulk region at a constant rate and receives a feedback of the bulk chemical from the entire collection of cells. This global feedback\, which activates signaling pathways within the cells\, modifies the intracellular dynamics according to the external environment. The cell secretion and global feedback are regulated by permeability parameters across the cell membrane. For arbitrary reaction-kinetics within each cell\, the method of matched asymptotic expansions is used in the limit of small cell radius to construct steady-state solutions of the PDE-ODE model\, and to derive a globally coupled nonlinear matrix eigenvalue problem (GCEP) that characterizes the linear stability properties of the steady-states. The analysis and computation of the nullspace of the GCEP as parameters are varied is central to the linear stability analysis. In the limit of large bulk diffusivity\, an asymptotic analysis of the PDE-ODE model leads to a limiting ODE system for the spatial average of the concentration in the bulk region that is coupled to the intracellular dynamics within the cells. Results from the linear stability theory and ODE dynamics are llustrated for Sel’kov reaction-kinetics\, where the kinetic parameters are chosen so that each cell is quiescent when uncoupled from the bulk medium. For various specific spatial configurations of cells\, the linear stability theory is used to construct phase diagrams in parameter space characterizing where a switch-like emergence of intracellular oscillations can occur through a Hopf bifurcation. The effect of the membrane permeability parameters\, the reaction-kinetic parameters\, the bulk diffusivity\, and the spatial configuration of cells on both the emergence and synchronization of the oscillatory intracellular dynamics\, as mediated by the bulk diffusion field\, is analyzed in detail. The linear stability theory is validated from full numerical simulations of the PDE-ODE system\, and from the reduced ODE model when is large. \nJoint work with Sarafa Iyaniwura (UBC) and Jia Gou (UC Riverside). \nThe Dalhousie-AARMS Analysis-Applied Math-Physics Seminar takes place on Fridays from 4 – 5 pm Atlantic Time over Zoom.  If you would like to attend\, please email the organizers for connection details.

SUMMARY:AARMS COVID-19 Seminar: Amy Hurford (MUN)
DESCRIPTION:Modelling the impact of travel restrictions on COVID-19 cases in Newfoundland and Labrador\nImported infections disproportionally contribute to coronavirus disease 2019 (COVID-19) outbreaks in regions where infection prevalence is low. On May 4th\, Newfoundland and Labrador implemented travel restrictions whereby non-residents could enter NL only with exemptions. As the prevalence of COVID-19 was low at the time\, it is likely that the travel restrictions substantially reduced the COVID-19 epidemic in NL.  We fit a stochastic epidemic model to data describing the number of active COVID-19 cases in NL from March 14th – May 4th. We then forecast the distribution of outbreak sizes over the 9 weeks subsequent to May 4th\, with and without the travel restrictions\, and for physical distancing scenarios ranging from a 40% to 70% reduction in the daily contact rate relative to pre-pandemic levels. The implementation of travel restrictions in NL resulted in a 20-fold decrease in the number of cases over the subsequent 9 weeks. Assuming that physical distancing reduced the contact rate to 55% of its pre-pandemic level\, the median number of cases without the travel restrictions was 19 and with the travel restrictions was 1. Using epidemic modelling\, we show how the NL outbreak would have unfolded had travel restrictions not been implemented. The few COVID-19 cases reported following the implementation of travel restrictions is not evidence that the travel restrictions were unnecessary; rather our modelling shows that the travel restrictions are a plausible reason why there were few reported cases in NL in the 9-weeks after May 4th. \nThis is a virtual zoom seminar.  If you would like to attend\, please email the organizers for connection details.

SUMMARY:Atlantic GR Seminar: Nicholas Layden (Dalhousie) and Sharmin Akhter (MUN)
DESCRIPTION:Geometric Horizons in the Szekeres Spacetime\nNicholas Layden (Dalhousie University)\nA new conjecture for geometric horizons has been introduced which may provide a potential alternative to using apparent horizons and related surfaces for analyzing the dynamics of black hole spacetimes. In particular\, using two examples of black hole formation in a collapsing universe in the Szekeres spacetime\, the formation\, evolution\, and detection of geometric horizons are shown. In addition\, a function for detecting apparent horizons in the Szekeres spacetime is also considered\, and it is shown that the apparent horizon in the Szekeres model\, is in fact\, a geometric horizon. The Cartan-Karlhede algorithm for determining local equivalences of spacetimes is used to compute an invariant frame in the Newman Penrose frame formalism\, and Cartan invariants derived from the spacetime in this frame are shown to detect the geometric horizons under various conditions on the curvature tensors of the spacetime. One model for primordial black hole formation and another for galactic black hole formation are considered with non-zero cosmological constants\, generalizing work published previously on these models with zero cosmological constant. Future work utilizing geometric horizons may provide benefits in gravitational wave research involving black hole mergers. \nRigidity of Marginally Outer Trapped Surfaces in RNdS Spacetime\nSharmin Akhter (Memorial University of Newfoundland)\nWe investigate the rigidity of MOTS in four dimensional Reissner-Nordstrom-de Sitter spacetime. This is connected to the study of the first order derivative of stability operator (and hence the second derivative of outgoing null expansion). Since the stability operator has a zero eigenvalue in our case\, we use the Lyapunov-Schmidt reduction to establish rigidity. \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.

SUMMARY:PIMS/AARMS WORKSHOP ON New Trends in Localized Patterns in PDEs
DESCRIPTION:Mathematical Theory and Applications to Physics\, Biology and the Social Sciences– a Conference in Honour of the 60th Birthday of Michael J. Ward \nLocalized spatial-temporal patterns commonly occur for various classes of linear and nonlinear diffusive processes. In particular\, they occur in reaction-diffusion (RD) systems modeling quorumsensing (QS) behavior in biological systems\, the initiation of root-hair tip formation in plant cells\, and the spatial distribution of urban crime. Localization behavior also occurs in the biophysical context of calculating first passage statistics for a Brownian walker in a region with localized traps\, and in ecology for calculating the persistence threshold of a species in a patchy landscape. In recent years\, we have witnessed an explosion of many new and exciting developments in the theory and applications of localized solutions in PDEs. Many new frontiers have opened while new connections between old fields have been discovered. \nThis workshop will highlight Prof. Ward’s influential contributions to the mathematics and applications of localized solutions to PDEs. It brings together his students\, colleagues and collaborators in a celebration of Prof. Ward’s 60th birthday. Over his long career\, Prof. Ward has made numerous invaluable contributions to many areas of applied mathematics\, including fluid dynamics\, metastability\, reaction-diffusion equations\, cell biology and pattern formation. He has supervised 13 doctoral students and also mentored numerous postdocs and undergrads.

SUMMARY:Math Kitchen Party: organized by Connie Stewart (UNB Saint John)
DESCRIPTION:Hierarchical linear model with power law function on transmission of COVID-19 in Italy: Modelling and regression analysis\nYoutian Hao (UNB Fredericton)\nCOVID-19 growth data were typically collected from each region of a country\, and the transmission rate usually varies in different area. By adopting a power law with exponential cutoff function into hierarchical linear model\, it becomes possible to reveal the relationship between COVID-19 transmission rate and some regional level covariates of interest. A two-level hierarchical linear model is constructed\, where the first level includes a PLEC function with Poisson link\, and the second level incorporates parameters from level-one with regional level covariates. Modelling and regression analysis approach is implemented based on the model with Italian COVID-19 transmission data. \nWhy Most Published Research Findings Are False\nHugh Chipman (Acadia)\nMany scientific studies declare a “statistically significant” result but then can’t be replicated. What’s going on? Can we no longer trust statistics? Is this the end of the world as we know it? \nMusical Guests\n\nMichele Millar (MSVU)\nAugusto Suarez Garcia (UNBSJ)\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:Diversity in Mathematics 2020
DESCRIPTION:We propose a multi-year\, multi-level approach to promoting diversity and inclusivity in STEM. The annual two-week program encompasses concurrent\, partially overlapping events targeting two distinct groups: \n(a) A summer school for top undergraduate women in Canada and the northwest United States\, specializing in mathematics or a related STEM field such as computer science\, physics and statistics. The program will expose them to the many facets of the mathematical sciences in an intense two week immersion. Career opportunities in academia and industry will be given equal emphasis. We hope to encourage these gifted young women to continue on to graduate school\, an arena where women are still seriously under-represented. \n(b) An interactive math camp that runs as a companion program to the summer school. The target demographic here involves high school students in grades 10 and 11\, irrespective of gender\, with an aptitude for science and mathematics but from under-privileged groups.

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.

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: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: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: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: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: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 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:Math Kitchen Party: organized by Patrick Reynolds (UNB Fredericton)
DESCRIPTION:Source Sink Diffusion\nDanielle Cox (MSVU)\nWe 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). \nMore Fun with the Sierpinski Relatives\nTara Taylor (StFX)\nThe Sierpinski gasket is a well-known fractal that can be described as the attractor of an iterated function system (IFS) that maps the unit square to three smaller squares (scaled down by 2). A Sierpinski relative is a fractal that is an attractor of an IFS that maps the unit square to three smaller squares but also involves the symmetries of the square. This is an interesting class of fractals because they all have the same fractal dimension but different topologies. Some are totally disconnected\, some are disconnected with straight line segments\, some are simply-connected\, and some are multiply-connected. This very brief talk will explore different ways to compare and characterize the fractals that go beyond the fractal dimension. We will focus on the subclass that are disconnected with straight line segments\, and this will involve convex hulls and epsilon-hulls. \nMusical Guests\n\nPatrick Reynolds\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 CRG conference on Computational Aspects in Finance and Actuarial Sciences
DESCRIPTION: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 timely topics in finance and actuarial sciences. Our intention for this conference is to have a broad scope in terms of applications in Finance and Actuarial Sciences but we would like to put emphasis on numerical and computational issues (including trendy topics such as machine learning algorithms in finance and insurance\, but also more traditional methods such as numerical solutions for PDEs\, Monte Carlo simulations\, etc). The conference will include a dynamic program with high quality speakers focusing on innovative research\, policy discussions\, and business challenges and successes.

SUMMARY:Math Kitchen Party: organized by Tim Alderson (UNB Saint John)
DESCRIPTION:Pokemon in the City\nDanny Dyer (Memorial University of Newfoundland) \nWhen 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!  [Joint work with Jared Howell\, Grenfell Campus\, Memorial University.] \nPassing the buck: a chip firing game\nM.E. Messenger (Mount Allison)\nSuppose a group of people sitting in a row\, each take out their wallets and count their money. Then the richest person (or people)\, pass a dollar to their neighbours. Lather\, rinse\, repeat. We will discuss some of the dynamics of such a process and present a few results. We’ll also pose some questions and welcome solutions from the audience.

SUMMARY:CMS Special Session: Graph Decompositions
DESCRIPTION:Decomposition of graphs\, particularly decomposition into cycles\, is a vibrant area of research in the intersection of graph theory and the theory of combinatorial designs. For almost two centuries\, professional as well as amateur mathematicians have been intrigued by problems that are easy to state yet extremely difficult to solve. In the last couple of decades\, we have witnessed an explosion of new results\, including new techniques and solutions to many long-outstanding problems; however\, many fundamental problems remain unsolved. \nThe session in Graph Decompositions at the CMS 75th Anniversary Summer Meeting will bring together leading and emerging researchers in the field to share their recent results\, techniques\, and applications. \nThis session is dedicated to Louise Duffield Cummings\, a Canadian-born mathematician who contributed influential results in the study of triple systems. The year 2020 marks the 150th anniversary of her birth.
