Math Kitchen Party: organized by Asmita Sodhi (Dalhousie) and Rebecca McKay (UNB Saint John)
Tips and Tricks for Online Teaching Rebecca McKay (UNB Saint John) Many of us will be teaching with some online component in Fall 2020. In this brief talk, I will outline some tips and tricks for moving mathematics and statistics course activities into the virtual environment. Open Discussion Session: 8:30-8:50 This is a virtual zoom meeting. If you would like to attend, please email the organizers for connection details.

Slow decay of waves in gravitational solitons Sharmila Gunasekaran Gnanam Memorial University of Newfoundland Gravitational 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…

Diversity in Mathematics 2020
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: (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…

Simple epidemic models with importation Many provinces and territories have controlled the spread of SARS-COV-2 within their borders and are now weighing the risks and benefits of reopening internally and externally. In this week's seminar I'll lay out some groundwork for this comparison using variations on the simple SIR model. This is a virtual zoom seminar. If you would like to attend, please email the organizers for connection details.

Hierarchical linear model with power law function on transmission of COVID-19 in Italy: Modelling and regression analysis Youtian Hao (UNB Fredericton) COVID-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,…

Mathematical Theory and Applications to Physics, Biology and the Social Sciences– a Conference in Honour of the 60th Birthday of Michael J. Ward Localized 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…

Geometric Horizons in the Szekeres Spacetime Nicholas Layden (Dalhousie University) A 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…

Modelling the impact of travel restrictions on COVID-19 cases in Newfoundland and Labrador Imported 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…
