In 1993, Roberto Camassa and Darryl Holm, then at Los Alamos National Laboratory, published a paper, “An integrable shallow water equation with peaked solitons”, in a prime physics journal, Physical Review Letters, about a new candidate for the shallow water equation with a non-linear dispersion term. The equation they proposed is called the Camassa-Holm equation, abbreviated below as (CH). The paper has had a monumental impact on a legion of researchers in many different areas of mathematics, ranging from Analysis, Mathematical Physics, Random Matrix Theory, Approximation Theory, and Theory of Orthogonal Polynomials, to name a few. To celebrate this important discovery, our session brings together more than one generation of researchers working on many mathematical theories and problems rooted in the CH paper. | |

Erdos-Ko-Rado Combinatorics | |

Org: Karen Meagher and Venkata Raghu Tej Pantangi (University of Regina) | |

The famous Erdos-Ko-Rado (EKR) theorem gives the size and structure of the largest collection of intersecting k-sets. Versions of this theorem exist for many different objects, and there are many extensions and generalization of this result and n recent years the number of results in this area has grown greatly. The purpose of this session is to bring together researchers in this area to share recent results and approaches. The focus will be on algebraic method to prove EKR theorems, recent result on EKR for groups, EKR on designs and in geometry and EKR on graphs.

Org: Mahmud Azam (University of Saskatchewan), Kuntal Banerjee (University of Saskatchewan), Robert Cornea (University of Waterloo), Ha Minh Dat (University of Saskatchewan) and Brady Ali Medina (University of Waterloo) | |

Interactions between representation theory and geometry have been a major driving force for both areas. These interactions have been fruitful in computing invariants of important objects in both fields, each benefiting from results obtained in the other. These interactions are mediated by functors between categories relevant to the two fields, which are often homotopically invariant given suitable notions of homotopy on both sides. It is thus no wonder that homotopy theory and homotopical algebra have been applied to geometry and representation theory to great effect resulting in the ongoing generalisation and simplification of many of the most important concepts and results. These continue to facilitate advances in moduli theory and mathematical physics. The theme of the proposed session is this collective picture of geometry, homotopy theory, representation theory, moduli theory and mathematical physics. Furthermore, many recent contributions in these areas have been made by early career researchers, and it is the purpose of this session to highlight these efforts and to encourage mathematical exchanges between these researchers. | |

Quantization is a fundamental process in mathematical physics that lies at the heart of translating classical systems into the language of quantum mechanics. Integrable systems, with their rich symplectic structures and conserved quantities, provide a natural bridge to the quantum realm through the process of quantization. This session will serve as a platform for mathematicians, researchers, and enthusiasts to engage in stimulating discussions, share novel insights, and foster collaboration within these dynamic fields. The goal of this session will be to discuss deep connections between geometry and modern physics that offer insight to further work in both disciplines. | |
