Synchronization in Flocks with Large Population

Date: 28 November 2012
Speaker: Professor GUO Lei


To understand how locally interacting agents lead to collective behaviors is a fundamental issue in complex systems. Such problems arise from diverse fields ranging from material and life sciences to social and engineering systems, and have attracted much research attention in recent years. In this lecture, we will consider the synchronization problem of some basic classes of flocks with large population, without resorting to any connectivity assumptions imposed on the dynamical trajectories of the flocks. Furthermore, we will consider how to intervene the collective behaviors of the flocks without changing the existing interaction rules of the agents. The main theorems are established based on analyses of the nonlinear dynamical equations involved and of the asymptotical properties of the spectrum of the corresponding random graphs.
