SUMMARY:Changhui Tan\, NC State\, Self-organized dynamics: aggregation and flocking
DESCRIPTION:Self-organized behaviors are commonly observed in nature and human societies\, such as bird flocks\, fish swarms and human crowds. In this talk\, I will present some celebrated mathematical models\, with simple small-scale interactions which lead to the emergence of global behaviors: aggregation and flocking.\n\nI will discuss the models in different scales: from microscopic agent-based dynamics\, through kinetic mean-field descriptions\, to macroscopic fluid systems. In particular\, the macroscopic models can be viewed as compressible Euler equations with nonlocal interactions. I will show some recent results on the global wellposedness theory of the systems\, large time behaviors\, and interesting connections to some classical equations in fluid mechanics.\n
