This study explores chaotic synchronization in large networks. Researchers found that chaotic synchronization remains stable as network size increases, especially with external driving or global coupling.

Area of Science:

Complex Systems
Network Science
Nonlinear Dynamics

Background:

Investigating synchronization phenomena in large-scale networks is crucial for understanding complex systems.
Previous studies have focused on smaller networks or different coupling schemes.

Purpose of the Study:

To analytically and numerically study chaotic synchronization in n-dimensional large map networks.
To determine the size stability of these networks as the node number approaches infinity (N-->infinity).

Main Methods:

Analytical investigation of synchronization stability.
Numerical simulations to observe network state transitions.

Main Results:

Chaotic synchronization is analytically shown to be stable for N-->infinity with external driving or global coupling.

Numerical results reveal a route of network states: spatiotemporal chaos, cluster synchronization, complete synchronization, spatiotemporal patterns, and back to spatiotemporal chaos as interaction strength increases.

Conclusions:

Large map networks exhibit stable chaotic synchronization under specific conditions.
The interaction strength plays a critical role in determining the emergent network states, showing a complex transition pathway.
