(color online). Different synchronization regimes for a set of 1000 noisy DF oscillators. Pictured are the values of global activator A (red line), the mean oscillator value 〈x〉 (dashed blue line), and ten randomly selected oscillator trajectories xn(t) (yellow lines). (a) Absence of synchronization for τ = 0. Other parameters are η = 0.2, ν = 0.2, γ = 1, β = 1, and X0 = 5. (b) Two-cluster regime for τ = 0.5 and other parameters the same as above. (c) Single-cluster regime for τ = 2.
