Synchronization on Riemannian Manifolds: Multiply Connected Implies Multistable

This article concerns the evolution of multiagent systems on networks over Riemannian manifolds. The motion of each agent is governed by the gradient descent flow of a disagreement function that is a sum of (squared) distances between pairs of communicating agents. Two metrics are considered: geodesic distances and chordal distances for manifolds that are embedded in an ambient Euclidean space. We...
