Jan Haškovec (KAUST):
Asymptotics of alignment and consensus models with delays
Abstract:
We study the impact of communication or reaction delays on the long-time behavior
of alignment/consensus models of Cucker-Smale type. For a model where agents
interact with each other through normalized communication weights,
we provide sufficient conditions for asymptotic flocking, i.e., convergence to a
common velocity vector, based on a construction of a suitable Lyapunov functional.
For a model without normalization, we present new stability estimates
for the particle flow, relating suitable delayed and non-delayed quantities.
We also briefly explain how multiplicative noise affects the long-time
dynamics and present results of systematic numerical simulations.
