The Hamiltonian mean field model of coupled inertial Hamiltonian rotors is a prototype for conservative dynamics in systems with long-range interactions where the interactions between the rotors are governed by a network described by a weighted adjacency matrix and it is found that the transition to synchrony begins when the coupling constant K is inversely proportional to the largest eigenvalue of the adjACency matrix.
Delay-induced Turing-like waves for one-species reaction-diffusion model on a network
