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: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: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: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: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.
