Improved bounds for zeros of the chromatic polynomial on bounded degree graphs
About 20 years ago Sokal proved that there exists a constant C so that for any graph G, all of the complex zeros of its chromatic polynomial are contained in the disk of radius C Delta(G) centered at 0. (Here Delta(G) denotes the maximum degree of G.) He showed that C could be taken slightly smaller than 8. This was improved to 6.91 by Fernández and Procacci. In this talk I will present an improvement to 5.02 and explain some of the ideas and ingredients of the proof.
Based on joint work with Maurizio Moreschi, Viresh Patel and Ayla Stam.

Group equivariant neural networks seen by a mathematician
Artificial neural networks (ANNs) are incredibly successful at performing certain machine learning tasks, such as classification. In applications such as computer vision or quantum chemistry, we will often seek machine learning algorithms that can handle inputs that are transformed. For example, a cat detector should be able to detect a rotated cat.
Group theory provides the natural formalization of what we mean by transformations and group equivariance is the property we seek in artificial neural networks (ANN) and there is currently a flurry of research activity in group equivariant neural networks. In this talk, I will present the M.Sc. work of my former student Max Hennick, which gives a characterization of (approximate) G-equivariant linear mappings. What is most striking is how effective a bit of functional analysis and algebra can be at answering this question.
I will provide as many examples as possible and conclude with some hopefully interesting questions.

Title: Path decompositions of random directed graphs
In this talk we consider the problem of partitioning the edges of a digraph into as few paths as possible. The minimum number of paths needed in such an edge decomposition is called the path number of the digraph.
The problem of determining the path number is generally NP-hard. However, there is a simple (easy to compute) lower bound for the path number of a digraph in terms of its degree sequence, and a conjecture of Alspach, Pullman, and Mason from 1976 states that this lower bound gives the correct value of the path number for any even tournament. The conjecture was recently resolved, and in this talk I will discuss to what extent the conjecture holds for other digraphs. In particular I will discuss some of the ingredients of a recent result showing that the conjecture holds for almost all digraphs.
More generally we will see the conjecture holds with high probability for the random directed graph D_{n,p} for a large range of p. In fact the proof does not use randomness in a significant way.

This is joint work with Alberto Espuny Díaz and Fabian Stroh.

Title: Local eigenvalue statistics of random matrices and Dyson Brownian motion
Abstract: Dyson Brownian motion is a stochastic process describing eigenvalue dynamics under a matrix-valued Brownian motion. We will review this process and its role in the study of universality of the local
spectral statistics of random matrices. We discuss results on the local ergodicity of Dyson Brownian motion and applications, including local eigenvalue universality of the adjacency matrices of sparse random graphs
and an additive model related to free probability. Time permitting, we also review results on the universality of extremal spectral statistics and the fluctuations of a single eigenvalue in the spectral bulk.
The Dalhousie-AARMS Analysis-Applied Math-Physics Seminar takes place on Fridays from 4 – 5 pm Atlantic Time in Chase 319 on the Dalhousie University campus with some being broadcasted over Zoom. If you would like to attend, please email the organizers for connection details.

Title: The basics of the deduction game
Abstract:
The deduction game is a new variant of the classical chasers and runners game where the chasers are trying to catch an invisible runner quickly, but with no communication possible between chasers on different vertices. Instead, chasers may deduce where their fellow chasers *must* move, and make corresponding adjustments to their own movements. The goal is to use as few chasers as possible, and in some cases that number is quite high. We will examine some bounds on the deduction number, determine the deduction number of several classes of graphs, and pose some open problems. This is joint work with Andrea Burgess and Mozhgan Farahani.

In pursuit-evasion games, a set of pursuers attempts to locate, eliminate, or contain an evader in a network. The rules, specified from the outset, greatly determine the difficulty of the questions posed above. For example, the evader may be visible, but the pursuers may have limited movement speed, only moving to nearby vertices adjacent to them.
Central to pursuit-evasion games is the idea of optimizing certain parameters, whether they are the search number, burning number, or localization number, for example. We report on progress in several pursuit-evasion games on graphs and conjectures arising from their analysis. Finding the values, bounds, and algorithms to compute these graph parameters leads to topics intersecting graph theory, the probabilistic method, and geometry.

2021-09-20 15:00 - 16:30 (America/Halifax) | Zoom seminar
Modelling of disease spread through heterogeneous population
We present a simple model of disease spread that incorporates spatial variability in population density. Starting from first principles, we derive a novel PDE with state-dependent diffusion. Consistent with observations, this model exhibits higher infection rates in the areas of higher population density. The model also exhibits an infection wave whose speed varies with population density. In addition, we demonstrate the possibility of super-diffusive propagation of infection, whereby an infection can “jump” across areas of low population density towards the areas of high population density. Finally, a case study of coronavirus spread in the Canadian province of Nova Scotia is presented with qualitatively similar features as our model, including density-dependent infection rates and infection that jumps across main population centers.

Modelling immunity against SARS-CoV-2 from infection and vaccination: The Atlantic Bubble
We have developed a mathematical model model of COVID-19 in the population. The model is stratified over 5-year age groups, and by immunity status. We track mild, moderate, and severe infections by age, as well as vaccination uptake. The model is fit to COVID-19 case data, and produces estimates of immunity distributions for each age group, from infection and vaccination. In this talk I will provide a overview of the model, and we will discuss results specific to the Atlantic Bubble region.

AARMS Industrial Problem Solving Workshop 2021
2021-07-26 - 2021-08-06
The Atlantic Association for Research in the Mathematical Sciences (AARMS) will host its third Industrial Problem Solving Workshop (IPSW) in a purely online format from from July 26 to August 6
About IPSWs

The main goals of an IPSW are to build connections between researchers in industry, non-profit organizations, and academia. Organizations based in Atlantic Canada and elsewhere present problems related to their interests, and participants will break into teams to explore solutions to these problems. The problems come from a variety of subject areas, but all are designed to be approachable by students and postdocs with backgrounds in pure mathematics, modelling, scientific computing, computer science, or data analysis. Each problem group will be led by one or more university faculty members with expertise relevant to the technical challenge at hand, but participants with a wide range of interests and expertise are welcome. Over the course of the workshop, problem groups will work collaboratively to explore possible solution strategies to the technical challenges and propose longer-term research directions, as well as make connections to a larger group of companies and academic researchers with similar interests.

Event format

This year’s IPSW will be a little bit different from previous versions: it is two weeks in duration and convened exclusively online. Problem solving teams are invited to use AARMS video-conferencing resources to schedule their own problem solving sessions during the course of the workshop. It is expected that many people will participate on a part-time basis. We will plan to organize several optional live events during the course of the workshop aimed at networking and career-oriented skills training.

Prizes

NBIF Award for best problem solving pitch ($500 shared amongst student/postdoc presenters)
Springboard Atlantic Award for most valuable student/postdoc problem solver ($500 for one student)
AARMS Award for best solution ($2000 shared amongst student/postdoc members of the winning team)

Spatial-Temporal Modeling of COVID-19 Mortality Risk in Toronto, Canada
In this talk, a spatial-temporal model for modeling georeferenced COVID -19 mortality data in Toronto, Canada will be presented. A range of factors and spatial-temporal terms are incorporated into the model. The non-linear and interactive effects of the neighborhood-level factors, i.e., population density and average of income, are modeled as a two-dimensional spline smoother. The change of spatial pattern over time is modeled as a three-dimensional tensor product smoother. By fitting this model, the space-time effect can uncover the underlying spatial-temporal pattern that is not explained by the covariates. The performance of the modeling method based on the individual data is also compared to the modeling methods based on the aggregated data in terms of in-sample and out-of-sample predictive checking. The results suggest that the individual-level based analysis provided a better overall model fit and higher predictive accuracy for detecting epidemic peaks as compared to the analysis based on the aggregated data in this application.

From Agent Based Infectious Disease Models to Compartment Models
There are lots of potential agent based approaches to COVID modelling, and it is of interest to try to connect them to more standard compartment ODE models. To what extent can any ODE model capture the properties of a given ABM? The Inhomogeneous Random Social Network (IRSN) framework I have developed recently provides an explicit setting where such questions can be explored mathematically. The IRSN approach starts with a finite number N of heterogeneous agents that interact according to AB type rules. Under some conditions, one can analyze their large N limit, and under even more conditions, derive a limiting standard stratified compartment ODE model. The IRSN framework can be made arbitrarily fine-grained in many dimensions, including demographic classification, immunology (multiple variants), contact settings (types of contact locations) but only certain combinations of features are relevant to the ODE limit. ABMs capture characteristics such as non-homogeneous mixing that are not easily captured in any ODE model, so they help to understand the impact of such characteristics on disease propagation.

Using a Mathematical Model to Investigate the Efficacy of Asymptomatic Testing to Detect SARS-CoV-2
A mathematical model was constructed to investigate the efficacy of asymptomatic testing for SARS-CoV-2 detection. Preliminary data suggests that the stage of disease at the time of testing impacts its efficacy. The probability of being detected by the asymptomatic test was compared by the number of days waited until taking the test since arrival given the unknown state of disease at arrival, the variability of the infectious period and whether case detection efforts were undergone prior to arrival. It was found that if assuming an equal probability of being in the incubation stage or an asymptomatic infectious stage, waiting until the fifth day since arrival to be tested is the earliest testing date that results in more detected than undetected cases. Additionally, in the 50% of COVID-19 cases with an infectious period longer than 22 days, there are limited differences in the probability of being detected when tested within the first 2, 5 or 8 days since arrival.

Groups acting on Trees: minicourse by Olga Kharlampovich
2021-05-03 - 2021-05-07 | Online via Zoom
From May 3, 2021 to May 7, 2021, Professor O. Kharlampovich from City University of New York will teach a mini course on Groups acting on Trees. Due to the current situation caused by the corona virus disease, the mini course will take place virtually.
Bass-Serre theory relates group actions on trees with decomposing groups as iterated applications of the operations of amalgamated product and HNN extension, via the notion of the fundamental group of a graph of groups.
One of the generalizations of Bass-Serre theory is the theory of isometric group actions on real trees (R-trees) which are metric spaces generalizing the graph-theoretic notion of a tree. Group actions on R-trees arise naturally in geometric topology, as well as in geometric group theory. Asymptotic cones of groups often have a tree-like structure and give rise to group actions on real trees. The use of R-trees and $Lambda$ -trees, in particular Zn-trees, together with Bass-Serre theory, are key tools in the work on the elementary theory of a free group by Kharlampovich-Miasnikov and Sela.
The course will be suitable for undergraduates, graduate students, postdocs, faculty, and anyone interested in algebra. The internet address for the virtual meeting room will be available at https://www.mun.ca/aac/AACMiniCourses/olga/
The mini course will take place from 10 to 10:50 Eastern Standard Time.

A Simulation-Optimization Framework for Optimizing Response Strategies to Epidemics
Epidemics require dynamic response strategies that encompass a multitude of policy alternatives and that balance health, economic and societal considerations. We propose a simulation-optimization framework to aid policymakers select closure, protection and travel policies to minimize the total number of infections under a limited budget. The proposed framework combines a modified, age-stratified SEIR compartmental model to evaluate the health impact of response strategies and a Genetic Algorithm to effectively search for better strategies. We implemented our framework on a real case study in Nova Scotia to devise optimized response strategies to COVID-19 under different budget scenarios and found a clear trade-off between health and economic considerations. Closure policies seem to be the most sensitive to budget restrictions, followed by travel policies. On the other hand, results suggest that practicing social distancing and wearing masks are necessary under all scenarios. The framework is generic and can be extended to encompass vaccination policies and to use different epidemiological models and optimization methods.
