时滞小世界网络中的分形

Fractals in Small-World Networks With Time Delay

Xin-She Yang

摘要:

Watts和Strogatz最近提出的小世界网络[Nature 393,440(1998)]引起了人们对研究无时滞网络有趣性质的兴趣。然而,在小世界网络上传播的信号或影响通常与生物和物理网络中非常常见的时延特征相关联。我们开发了一种分析方法,以及数值模拟,试图描述的影响,时间延迟的小世界网络的属性。给出了小世界网络分形维数的解析表达式,并与数值模拟结果进行了比较。分析表明,具有时滞的小世界网络一般具有多重分形性质。

英文摘要:

The small-world networks recently introduced by Watts and Strogatz [Nature 393, 440 (1998)] has attracted much interests in studying the interesting properties of the networks without time-delay. However, a signal or influence travelling on the small-world networks often associated with time-delay features which are very common in biological and physical networks. We develop an analytical approach as well as numerical simulations to try to characterize the effect of time-delay on the properties of small-world networks. An analytical expression of the fractal dimension of the small-world networks is given and thus compared with the results from numerical simulations. Analysis shows that small-world networks with time-delay generally have the multifractals property.
