Synchronization between Two Discrete-Time Networks with Mutual Couplings

Figure 1

The panels exhibit 𝐸_𝑥,𝐸_𝑦, and 𝐸_outer at 𝑡=400 with regard to 𝑚_𝑥 for 𝑁=10 and 𝑚_𝑦=0.2. The bottom one shows that the inner synchronization inside network 𝑋 is easily achieved. When 𝑚_𝑥≥0.5, the inner and outer synchronization simultaneously appear.
