Panorama of Mathematics - Laure Saint-Raymond
Offered By: Hausdorff Center for Mathematics via YouTube
Course Description
Overview
Explore the fascinating world of particle dynamics in this 52-minute lecture by Laure Saint-Raymond titled "Exchangeability, chaos and dissipation in large systems of particles." Delve into the complexities of hard sphere dynamics, predictability in particle systems, and the concepts of ergodicity and invariant measures. Examine the role of entropy and chaos in large particle systems, and understand the mean field limit and its convergence to the Boltzmann equation. Investigate the low density limit, propagation of chaos, and fluctuations in particle systems. Analyze the relationships between correlations, dissipation, and mixing mechanisms. This talk, part of the "Panorama of Mathematics" conference organized by the Hausdorff Center for Mathematics, offers a comprehensive overview of current trends, results, and challenges in the mathematical sciences related to large-scale particle systems.
