Abstract

The {\em ss-energy} is a generating function of wide applicability in network-based dynamics. We derive an (essentially) optimal bound of (3/ρs)n1(3/\rho s)^{n-1} on the ss-energy of an nn-agent symmetric averaging system, for any positive real s1s\leq 1, where~ρ\rho is a lower bound on the nonzero weights. This is done by introducing the new dynamics of {\em twist systems}. We show how to use the new bound on the ss-energy to tighten the convergence rate of systems in opinion dynamics, flocking, and synchronization.
