Network synchronization: Spectral versus statistical properties

Abstract: We consider synchronization of weighted networks, possibly with asymmetrical connections. We show that the synchronizability of the networks cannot be directly inferred from their statistical properties. Small local changes in the network structure can sensitively affect the eigenvalues relevant for synchronization, while the gross statistical network properties remain essentially unchanged. Consequently, commonly used statistical properties, including the degree distribution, degree homogeneity, average degre… Show more

“…Moreover, in the system of coupled oscillators which we consider below, superior synchronization is essentially related to maximizing the second smallest eigenvalue of the graph Laplacian. This eigenvalue -the algebraic connectivity-is an important invariant for undirected graphs and is, e.g., relevant for the analysis of the robustness of networks against node removal or for epidemic spreading [3]. …”

“…Various studies have attempted to link network characteristics such as clustering [9,10,11,12], degree mixing [9,13], pathlength [14,15] or betweenness centrality [15,16,10] to the PFS. More detailed analyses, however, show that such a characterization is at most meaningful in a statistical sense, since synchronization appears to be determined by 'fine' details of the organization of the coupling network [17]. Thus, linking synchronization properties to statistical network measures often provides only a rule of thumb.…”
