Algebraic combinatorics: longstanding questions in symmetric functions  | |
| Org: Houcine Ben Dali (Harvard University), Angele Foley (Wilfrid Laurier University) and Alejandro Morales (Université de Québec à Montréal) | |
| The enumerative side of algebraic combinatorics has long focused on various symmetric functions and the interplay between them. For example, a key research question has been to characterize properties of the coefficients that result when transforming from one basis to another. In this session we focus on some fundamental symmetric function questions, with a particular focus on recent advances on longstanding open problems such as conjectures on Jack polynomials (b-conjecture, matching Jack conjecture, and Stanley’s conjecture on Littlewood-Richardson coefficients), positivity conjectures of chromatic symmetric functions, and Delta conjectures from diagonal harmonics. | |
| Analytic and Combinatorial Aspects in Convex and Discrete Geometry | |
| Org: Károly Bezdek (University of Calgary, Canada), Fodor Ferenc (University of Szeged, Hungary and University of Calgary, Canada) and Alina Stacu (Concordia University, Canada) | |
| This session will bring together researchers working in convex and discrete geometry from analytic and combinatorial perspectives, with emphasis on recent breakthroughs, geometric inequalities, packings and coverings, and applications to analysis and quantum information theory. It will be preceded by a CRM workshop featuring mini-courses and introductory lectures to prepare graduate students, postdoctoral researchers, and other early-career participants for the 2026 CMS Winter Meeting. Session speakers are encouraged to participate in the workshop, fostering interaction, mentoring, and collaboration across career stages. | |
| Applied and Computational Algebraic Geometry | |
| Org: Taylor Brysiewicz (University of Western Ontario), Greg Smith (Queen's University) and Maksym Zubkov (University of British Columbia) | |
| Polynomial systems are ubiquitous in mathematics, science, and engineering, making algebraic geometry a natural framework for studying their solution sets. This session will showcase recent developments in applied and computational algebraic geometry, ranging from the development of polynomial models for applications to symbolic and numerical methods for solving such systems. | |
| Around harmonic analysis: applications to number theory, geometric measure theory, PDE, and more | |
| Org: Suresh Eswarathasan (Dalhousie University) and Chamsol Park (University of Rochester) | |
| This session will be focused on the recent interplay of harmonic analysis with a variety of fields. Lectures will address, but are certainly not necessarily limited to, problems related to the Kakeya conjecture, local smoothing, eigenfunctions on compact manifolds, and prime counting. | |
| Combinatorial Design Theory | |
| Org: Andrea Burgess (University of New Brunswick Saint John) and Shuxing Li (University of Delaware) | |
| Combinatorial design theory explores how simple local balance conditions can give rise to remarkably rich global structure—turning elementary arrangements of finite sets into objects of deep mathematical interest. Over the past decades, the field has grown into a vibrant cornerstone of discrete mathematics, with far-reaching connections to graph theory, finite geometry, coding theory, and cryptography. The talks in this session showcase some of the most exciting recent developments in the area, offering a glimpse into the breadth, depth, and continuing vitality of modern design theory. | |
| Commutative Algebra | |
| Org: Giulia Gaggero, Lisa Seccia and Adam Van Tuyl (McMaster University) | |
| This special session is devoted to commutative algebra. Not only does commutative algebra contribute to the algebraic side of algebraic geometry, commutative algebra has connections to areas such as combinatorics, approximation theory, algebraic statistics, coding theory, and physics, among others. There is much collaboration going on between Canadian mathematicians and colleagues around the world on this topic, making such a session a great opportunity for the exchange of ideas. | |
| Dynamics and Symmetry | |
| Org: Archishman Saha (Present: University of Ottawa. Starting August 24th, University of Michigan) and Cristina Stoica (Wilfrid Laurier University) | |
| The aim of this session is to bring together researchers working in systems where symmetry is present. The scope includes both finite- and infinite-dimensional systems, such as ODEs, PDEs and non-local models. Possible topics include, but are not restricted to, bifurcations and stability, control, geometric and symmetry-preserving numerical methods and pattern formation. We welcome contributions involving applications to engineering systems, astrodynamics, coupled media (for example, fluid-elastic systems), fluid dynamics, plasma models, and other dynamical systems models displaying symmetry in the equations or analysis. | |
| Early-Career Researchers in Graph Theory | |
| Org: Kathie Cameron (Wilfrid Laurier University), Cicely Henderson (University of Waterloo) and Taite LaGrange (University of Waterloo) | |
| Featuring talks from early-career graph theorists, including Master’s students, PhD students, recent graduates, and post-docs, this session will highlight developments from new talent in the field of graph theory. The talks will cover recent advancements in structural, algorithmic, and extremal graph theory from these up-and-coming researchers. | |
| Geometric Problems in PDEs | |
| Org: Lia Bronsard and Kenneth DeMason (McMaster University) | |
| This session brings together leading researchers and emerging scholars to present recent advances in partial differential equations arising from geometric problems. Topics include, but are not limited to, minimal surfaces, geometric measure theory, isoperimetric problems, liquid drop models, and harmonic maps on manifolds. Emphasis will be placed on new analytical techniques, qualitative properties of solutions, and connections between geometric structure and PDE behavior. | |
| Mathematics of Machine Learning | |
| Org: Simone Brugiapaglia (Concordia) and Tim Hoheisel (McGill) | |
| Machine learning is transforming research, industry, and policymaking, but many of its mathematical foundations remain poorly understood. Despite the success of methods such as deep learning, challenges related to interpretability, stability, and the theoretical understanding of optimization algorithms highlight important gaps between theory and practice. This session aims to bring together experts in the mathematics of machine learning to discuss these challenges, foster collaboration, and explore emerging ideas in this rapidly evolving field. | |
