## TL;DR

This paper studies opinion dynamics on a one-dimensional lattice, demonstrating the existence of weak consensus without strong consensus in a generalized model lacking a central opinion.

## Contribution

It extends a known opinion model to a broader space, showing weak but not strong consensus can occur without global agreement.

## Key findings

- Existence of weak consensus without strong consensus on $\
- Model extension to a more general opinion space
- Demonstration of weak consensus without strong consensus in a 1D lattice

## Abstract

We investigate a model for opinion dynamics, where individuals (modeled by vertices of a graph) hold certain abstract opinions. As time progresses, neighboring individuals interact with each other, and this interaction results in a realignment of opinions closer towards each other. This mechanism triggers formation of consensus among the individuals. Our main focus is on strong consensus (i.e. global agreement of all individuals) versus weak consensus (i.e. local agreement among neighbors). By extending a known model to a more general opinion space, which lacks a "central" opinion acting as a contraction point, we provide an example of an opinion formation process on the one-dimensional lattice with weak consensus but no strong consensus.
