Convergence to Consensus for a Hegselmann-Krause-Type Model with Distributed Time Delay
Dipartimento di Ingegneria e Scienze dell'Informazione e Matematica, UniversitÓ di L'Aquila, 67010 L'Aquila, Italy
We study a Hegselmann-Krause opinion formation model with distributed time delay and positive influence functions. Through a Lyapunov functional approach, we provide a consensus result under a smallness assumption on the initial delay. Furthermore, we analyze a transport equation, obtained as mean-field limit of the particle one. We prove global existence and uniqueness of the measure-valued solution for the delayed transport equation and its convergence to consensus under a smallness assumption on the delay, using a priori estimates which are uniform with respect to the number of agents.
