复杂网络广义同步研究进展

The development of generalized synchronization on complex networks

Shuguang Guan, Xingang Wang, Xiaofeng Gong, Kun Li, C. -H. Lai

摘要:

本文研究了无标度网络、小世界网络、随机网络和模块化网络等典型复杂网络上的广义同步问题。通过采用混沌系统方法研究网络,我们证明了在具有异质和均匀度分布的振子网络中,无论耦合的混沌振子是相同的还是不同的,GS都可以发生。对于网络中的耦合同振子,随着耦合强度的增加,存在一条从初始非同步到最终全局完全同步的一般分岔路径.对于网络上的耦合非全同振子,我们进一步揭示了网络拓扑如何与局部动力学竞争,以主导网络上GS的发展。特别地,我们分析了不同的耦合策略如何影响复杂网络上的GS的发展。我们的研究结果为复杂网络中集体行为的发生和发展提供了进一步的认识。

英文摘要:

In this paper, we investigate the development of generalized synchronization (GS) on typical complex networks, such as scale-free networks, small-world networks, random networks and modular networks. By adopting the auxiliary-system approach to networks, we show that GS can take place in oscillator networks with both heterogeneous and homogeneous degree distribution, regardless of whether the coupled chaotic oscillators are identical or nonidentical. For coupled identical oscillators on networks, we find that there exists a general bifurcation path from initial non-synchronization to final global complete synchronization (CS) via GS as the coupling strength is increased. For coupled nonidentical oscillators on networks, we further reveal how network topology competes with the local dynamics to dominate the development of GS on networks. Especially, we analyze how different coupling strategies affect the development of GS on complex networks. Our findings provide a further understanding for the occurrence and development of collective behavior in complex networks.
