Synchronization in complex delayed dynamical networks with intermittent coupling

This present paper investigates synchronization dynamics of a general model of complex delayed dynamical networks with intermittent coupling. Some simple yet generic criteria for global synchronization of such intermittent coupled dynamical networks are derived analytically. It turns out that the coupled delayed dynamical networks can always achieve synchronization even there are connections among the nodes only at some discrete moments. Furthermore, the results are applied to a typical nearest neighboring coupled SF networks consisting of the chaotic delayed Hopfield neural network, and numerical simulations are carried out to verify and also visualize the theoretical results.
