Criterion for Unbounded Synchronous Region in Complex Networks

Figure 3

𝑋 label: 𝜎=−𝑐𝜆, 𝑌 label: Lyapunov Exponent of network (13), single node dynamics: Lorenz system, inner-coupling matrix: 𝐇₁ (a); 𝐇₂ (b); 𝐇₃ (c). The cross point 𝜎^∗₀ represents the lower bound of synchronous region in each subgraph.
