Abstract:
The Euler-alignment system describes the collective behaviors of animal swarms. In this talk, we introduce a new type of alignment interaction that depends nonlinearly on velocity. We explore the asymptotic flocking and alignment behaviors. Notably, the introduction of nonlinearity yields a spectrum of distinctive asymptotic behaviors. Moreover, we present a rigorous derivation of our system from a kinetic flocking model.
