Abstract

We consider the well known finite-dimensional Cucker–Smale system, modelling interacting collective dynamics and their possible convergence to consensus. The objective of this paper is to study the influence of time-delays in the general model on the convergence to consensus. By a Lyapunov functional approach, we establish convergence results to consensus for symmetric and nonsymmetric communication weights under some structural conditions.
