Advances in Operator Algebras
Org: Cristian Ivanescu (MacEwan), Zhuang Niu (U Wyoming) and Maria Grazia Viola (Lakehead)
Operator algebras—the study of algebras of bounded linear operators on a Hilbert space—is a significant branch of analysis that originated with John von Neumann and his collaborators in the early part of the 20th century as a mathematical framework for quantum mechanics. Since then, it has shown deep connections to other areas of mathematics, such as dynamical systems, geometry and topology, group theory, mathematical physics, quantum information theory, probability, etc. In this session, we welcome the participants to report on their recent advances in the field of operator algebras.

Data and Dynamical Systems
Org: Tanya Schmah (University of Ottawa) and Cristina Stoica (Wilfrid Laurier)
The intersection of data science with dynamical systems (including but not limited to ODEs and PDEs) is of increasing mathematical and scientific interest. On one hand it includes novel applications of data science to dynamical systems (e.g. data-driven model selection, approximate solution of DEs using deep learning, automatic detection of dynamical features) and on the other hand it entails novel uses of differential equations and dynamical system theory in machine learning (e.g. continuous-depth neural networks, PDE-based methods in computer vision). We propose to bring together researchers with interests in this area.

Descent Methods in Algebra, Geometry, and Topology
Org: Mikhail Kotchetov (Memorial), Dorette Pronk (Dalhousie), Yorck Sommerhäuser (Memorial) and Geoff Vooys (Dalhousie)
Descent theory is all about attempting to learn about a global structure by moving downwards to its local structure where we can determine things and then reassemble these local pieces together in a compatible way. In more modern language, the study of descent is often seen as the study of sheaves or generalizations of the sheaf condition, as what it means for pieces to be compatible can be generalized and adapted to myriad contexts in algebra, algebraic topology, algebraic geometry, category theory, and even in logic. Because researchers in all areas use descent-theoretic ideas in distinct ways, we seek to bring together mathematicians from different disciplines and different walks of life to share ideas and learn from each other. This session seeks to bring together experts in many different areas of mathematics together to teach each other and learn about different approaches while also introducing graduate students to descent theory and how it maybe applied in practice.

Geometric analysis and general relativity
Org: Hari Krishna Kunduri (Memorial) and Eric Woolgar (Alberta)
General relativity has long been a rich source of novel problems in differential geometry, partial differential equations, and dynamical systems. In turn, this has led to the development of new techniques in these fields that have produced rigorous proofs of physically motivated conjectures, such as the positive mass theorem and the nonlinear stability of Minkowski spacetime. Hyperbolic PDEs arise in the context of the Cauchy problem, whereas elliptic problems are naturally associated to the study of allowed initial data. Moreover, progress in the study of Einstein’s equations is closely connected with advances in the understanding of other geometric PDEs (e.g. Ricci flow). Our session will focus on new results in mathematical general relativity and associated geometric PDEs.

A recent trend in probability has revealed some equally fascinating geometric structure, particularly in various ensembles of random fields including linear combinations of Laplace eigenfunctions with Gaussian coefficients. This session will focus on the geometry of eigenfunctions and related random fields, particularly on the structure of their zero sets and complements, which are dubbed nodal sets and nodal domains, respectively. All aspects of spectral geometry, however, will be considered in this session.

Global Dynamics and Propagation Phenomena of Biological Systems
Org: Shuwen Xue and Xiaoqiang Zhao (Memorial)
Nonlinear dynamics and differential equations provide a powerful tool in modeling and understanding some biological phenomenon such as pattern formations, biological invasions, and disease transmissions. With an active group of researchers in these fields, more and more interesting phenomena have been described via various evolution systems, and the global dynamics and propagation phenomena of such systems have been investigated in order to gain insights on recently-emerged questions in biology including those in the context of climate changes and those related to the disease outbreak. While at the meantime, new challenging mathematical problems continue to arise from the study of these biological systems, which require further exploration. In this special session, we propose to invite some related scholars to present recent advances on the global dynamics and propagation phenomena of biological systems such as integro-differential equations, functional differential equations, lattice equations, reaction-diffusion equations, and nonlocal dispersal equations. This session will serve as a platform for leading experts and young researchers to exchange new ideas and initiate potential collaborations.

Harmonic Analysis and PDEs
Org: Scott Rodney (Cape Breton) and Eric Sawyer (McMaster)
The fields of Harmonic Analysis and Partial Differential Equations (PDEs) share a common history. Recently, regularity theory for degenerate nonlinear PDEs has been closely connected to several interesting areas including: quasi-conformal mappings, weighted norm inequalities, Orlicz classes, Hardy spaces and more. The focus of this session is to promote communication between researchers working in the many fields that touch upon the intersection of harmonic analysis and PDEs.

Learning Math Through Experimentation and Exploration
Org: Amenda Chow (York University), Allysa Lumley (Centre de Recherches Mathematiques) and Pam Sargent (York University)
The dictionary definition of experimentation is the process of performing scientific procedure, especially in a laboratory, to determine something. Exploration is defined as the action of traveling in or through an unfamiliar area in order to learn about it. This session looks at exploration and experimentation through the lens of mathematics.

Exploration and experimentation are examples of experiential learning. Students receive an indelible educational experience when exposed to experiential learning. Because of the perceived nature of mathematics there can sometimes be a lack of experiential learning in a mathematics education, especially when compared to other STEM disciplines like biology, and engineering that often have laboratory components, field work and internship placements.

The purpose of this session will be to help add more experiential learning through exploration and experimentation into the mathematics curriculum. This session is an opportunity to connect educators from all career levels and at both the post-secondary and high school level who have a desire to support experiential learning in the form of experimentation and exploration in their math courses and classrooms.

Modelling the emerging infectious diseases in wildlife
Org: Seyed M. Moghadas and Jingjing Xu (York University)
Emerging infectious diseases (EIDs) in wildlife not only thread the wildlife populations but also impact the balance of the local ecosystem. In addition, wildlife serves as reservoirs of pathogens, and infectious diseases may split over to human communities by direct contact with humans or indirectly impacting domesticated animals. Meanwhile, infections may spread in the other direction. Examples of EIDs in wildlife include zoonotic influenza, West Nile virus, emerging coronaviruses (e.g., severe acute respiratory syndrome (SARS), Middle East respiratory syndrome, and SARS-COVID-2), rabies, and Lyme disease. Studying EIDs usually face challenges due to the features of hosts, such as their demographic process, the seasonal spatial use or movement pattern, and the sex-age structure. Moreover, some EIDs involve multiple hosts. Nevertheless, mathematical models help us understand the characteristics of disease transmission and identify the driving factors, providing guidelines for the control or management of EIDs. This scientific session features a mixture of models that use various mathematical tools to capture the critical factors of disease transmission and hosts, and provide biological insight.

Scientific Machine Learning
Org: Ben Adcock (Simon Fraser), Alex Bihlo (Memorial University), Simone Brugiapaglia (Concordia) and Hamid Usefi (Memorial University)
Machine learning is having a profound impact on many different sectors including scientific research, industry, and policymaking. Yet, its mathematical foundations are still far from being well understood. While techniques such as deep learning have produced outstanding success on a wide range of real-world applications, it is increasingly well known that such methods tend to exhibit instabilities and generally lack in interpretability. Moreover, although stochastic optimization algorithms are ubiquitous in machine learning, their convergence properties are still not fully understood in the nonconvex framework. These and other gaps between theory and practice raise the pressing need for broader, more comprehensive mathematical foundations for machine learning.

The aim of this proposed session is to bring together a diverse group of leading experts in scientific machine learning. The proposed session will be a forum for discussing and exploring emerging ideas in this fast-growing and exciting field.

To OER or not to OER – that is the question
Org: Andrijana Burazin (University of Toronto Mississauga) and Miroslav Lovric (McMaster University)
UNESCO defines Open Educational Resources (OER) as “teaching, learning and research materials in any medium – digital or otherwise – that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions.”

This session has two goals: (i) to enable participants to discuss their experience with creating and/or using OERs, as well as to share information about where they look for OERs (there is no single repository, nor a site that would offer access or information for many OERs); (ii) to critically, and possibly with evidence, examine the place of OERs in mathematics instruction. What are good (also inappropriate) ways of using OERs in the classroom? Could OERs possibly replace in-person instruction? If so, at what cost, pedagogical and otherwise?

Ungrading and alternative assessments: shifting from grades to learning
Org: Xinli Wang (University of Manitoba)
Assessments have always been an important part of course design in higher education and K12 education. We rely on assessments to find out what students are learning, to communicate what is important to learn, to guide students’ learning journey, and to measure whether students have mastered the concepts and skills that are taught in a certain course. Traditionally, students take summative assessments: quizzes, term tests, mid-term and final exams and are assigned numerical grades after taking such assessments, and those numbers ultimately translate to a letter on their transcript. However, grades undermine interest and foster fear of failure. Students are also tempted to study or work for the grade rather than for learning. Grades have become a huge contributor to students’ stress and mental health problems. Grading is a system that is designed to categorize certain students as smarter than others, and is prone to cultural, racial, and societal biases. In this session, we will share our experiences with alternatives methods of assessment designed to communicate with students about their learning. The topics in this session include mastery-based grading, contract grading, using portfolios, group exams etc. When we design our course assessments, we have a common goal in mind: to foster growth mindset and encourage students to focus on their learning, instead of grades.
