TL;DR

This paper investigates nonlocal opinion dynamics on a circular agent network with attractive and repulsive interactions, identifying three consensus types and analyzing the transition mechanisms between them.

Contribution

It introduces a model capturing multiple consensus states in circular opinion dynamics with attractive and repulsive forces, revealing new transition phenomena.

Findings

Identified three types of consensus: global, local, and chimera.

Discovered a scaling law relating opinion difference and interaction radius.

Demonstrated transitions between local and chimera consensus states.

Abstract

In this work, we study a nonlocal opinion dynamics in a ring of agents with circular opinion in the presence of both attractive and repulsive interactions. We identified three types of consensus in this model, including global consensus, local consensus, and chimera consensus. In global consensus, both local agreement among adjacent agents and global agreement among all agents are achieved. In local consensus, local agreement is satisfied but global agreement fails. There are two domains in chimera consensus, one preserves local agreement and the other breaks the local agreement. The relation between the opinion difference between adjacent agents and the interaction radius is investigated and a scaling law is found. The transitions between local consensus and chimera consensus are exemplified.
