TL;DR

This paper introduces a modified velocity alignment model on quotient spaces of Euclidean space, utilizing all geodesics for interactions to relax prior constraints, and explores emergent behaviors on specific manifolds.

Contribution

It proposes a new model that uses all geodesics for interactions, removing previous restrictions and analyzing effects of topology on emergent behaviors.

Findings

Model works on various manifolds like torus, M"{o}bius strip, Klein bottle

Relaxed conditions on particles' positions and communication functions

Demonstrated influence of topology on emergent behaviors

Abstract

The Cucker-Smale(CS) model is a velocity alignment model, and this model also has been generalized on general manifolds. We modify the CS model on manifolds to get rid of a-priori condition on particles' positions and conditions on communication functions. Since the shortest geodesic is used to define an interaction between two particles, if there exist two or more than two shortest geodesics, then the system is not well-defined. In this paper, instead of using the shortest geodesic to define an interaction between two particles, we use all geodesics to define an interaction. From this assumption, we can relax the a-priori condition and conditions on communication functions. We also explain the relationship between the suggested model and previous models. Finally, we provide some emergent behaviors on some specific manifolds(e.g. flat torus, flat M\"{o}bius strip, and flat Klein bottle). From these results, we can discuss the effect of the topology of the domain.
