Abstract:
We consider the role of topological dimension in problems of network
consensus and vehicular formations where only local feedback is available.
In particular, we consider the simple network topologies of regular lattices
in 1, 2 and higher dimensions. We address the question of rigidity of such
formations, or in other words, how closely do such formations resemble solid
objects. A common phenomenon appears where in dimensions 1 and 2, rigid
formations are impossible in the presence of any amount of additive stochastic
perturbations, and in the limit of large formations. In dimensions 3 and higher,
tightformationsareindeedpossible!Weshowthatmicroscopicerrormeasures
