| The simulation of real-life systems can be computationally expensive when a high precision is needed. Many modern approaches aim to reduce the computation time of large-scale simulation problems arising from high-dimensional discretized PDEs, dynamical systems, and complex networks, for instance. The goal of this session is to join together researchers working on methods to accelerate or enhance the numerical solution of applied problems while preserving theoretical guarantees of their accuracy. Such methods include (but are not limited to) reduced-order modeling, statistical and machine learning, improved iterative schemes, domain decomposition, high-performance computing, preconditioning, and uncertainty quantification. | |

| Org: Ludovick Bouthat (Laval), Steve Kirkland (University of Manitoba) and Hermie Monterde (University of Manitoba) | |
| Matrix theory, spectral graph theory, and operator theory are interconnected fields that continue to drive advancements in pure and applied mathematics. To study these connections, the session focuses on recent progress in these areas, with an emphasis on matrix analysis. By studying the algebraic and spectral properties of matrices, researchers gain insight into fundamental questions in mathematical physics, numerical analysis, and combinatorial optimization. | |

| The goal of this session is to bring together the group of experts working in the field of Stochastic Ordinary and Partial Differential Equations and related (and tightly interconnected) fields of Stochastic Analysis, Harmonic Analysis and PDEs. The latter include singular SDEs and PDEs in local and non-local settings, kinetic and many-particle models, the corresponding Hardy inequalities and Morrey estimates and heat kernel bounds. The area witnessed a rapid progress in the past few years, in particular, due to newly found connections to statistical-mechanical and biological models, progress in quantifying the emergence of the ""large scale"" stochastic dynamics such as mean field and hydrodynamic limits, advances in understanding the critical regimes of Kolmogorov and Fokker-Planck equations. | |

| Equity, Diversity, Inclusion, and Belonging in the Undergraduate Mathematics Classroom | |
| Org: Matthew Coles, Lindsey Daniels and Nahid Walji (UBC) | |
| It is well known that STEM fields consistently lack diversity (Fry, 2021). In particular, traditionally underrepresented groups are at a particularly high risk of STEM-attrition (Chen, 2013) and experienced differential impacts during pandemic instruction (Brown, 2022). We hope that this session will be an opportunity for undergraduate mathematics educators to share strategies for enhancing equity, diversity, inclusion, belonging both inside and outside the classroom. | |
