Abstract:

Interacting particle systems appear in physics, biology, and social dynamics, often leading to high-dimensional models. This minisymposium focuses on recent advances in model reduction techniques that enable efficient simulation, analysis, and interpretation of such systems. Approaches include mean-field models and stochastic PDEs, transfer-operator frameworks and Markov state models, hybrid multiscale models, coherent structure analysis, as well as data-driven techniques. The session aims to bring together theoretical and applied perspectives on efficient representations of complex, many-body systems.
