Emergent Behavior in Collective Dynamics

Explore a comprehensive lecture on emergent behavior in collective dynamics, delivered by Eitan Tadmor at the 2022 Virtual Joint Mathematics Meetings. Delve into various examples of emergence involving living agents and collective dynamics, covering fundamental concepts such as alignment, opinion dynamics, flocking, swarming, and synchronization. Examine the role of communication kernels, anticipation in alignment, and the 3 Zone model. Investigate questions about alignment dynamics, large-time behavior, and graph connectivity. Analyze emergent behavior instability, large crowd dynamics, hydrodynamic descriptions, and energy fluctuations. Discover the implications of short-range interactions and topological kernels. Gain insights into how different fields approach collective dynamics, with a focus on the role of empirical data in biology.
