具有度相关的无标度网络的同步

Synchronization in Scale Free networks with degree correlation

Cristian E. La Rocca, Lidia A. Braunstein, Pablo A. Macri

摘要:

本文研究了度-度相关无标度网络的同步过程模型。Pastore y Piontti { \it et al.}已经在这种没有相关性的网络上研究了这个模型,E { \bf 76},046117(2007)。在这里,我们研究的度度的相关性的行为上的负载波动$W_s$在稳定状态的影响。我们发现,对于非线性网络,存在一个特定的相关性,其中系统是最佳同步的。此外,我们发现,接近这个最佳值的波动不依赖于系统的大小,因此系统变得完全可扩展。这一结果对于某些技术应用可能非常重要。另一方面,远离最佳相关性,$W_s$与系统大小成比例关系。

英文摘要:

In this paper we study a model of synchronization process on scale free networks with degree-degree correlations. This model was already studied on this kind of networks without correlations by Pastore y Piontti {\it et al.}, Phys. Rev. E {\bf 76}, 046117 (2007). Here, we study the effects of the degree-degree correlation on the behavior of the load fluctuations $W_s$ in the steady state. We found that for assortative networks there exist a specific correlation where the system is optimal synchronized. In addition, we found that close to this optimally value the fluctuations does not depend on the system size and therefore the system becomes fully scalable. This result could be very important for some technological applications. On the other hand, far from the optimal correlation, $W_s$ scales logarithmically with the system size.
