时间富人俱乐部现象

The Temporal Rich Club Phenomenon

Nicola Pedreschi, Demian Battaglia, Alain Barrat

摘要:

识别代表复杂物理系统的网络的隐藏组织原则和相关结构是理解其属性的基础。为了达到这个目的,揭示网络中涉及网络的显著节点的结构是一种有效的方法。在时间网络中,连接的连续性对于时间稳定结构的出现至关重要。因此,我们在这里提出了一种新的措施,定量研究的趋势,连接良好的节点,形成同时和稳定的结构,在时间网络。我们把这种趋势称为“时间富人俱乐部现象”。我们说明了这个概念的兴趣,通过分析不同的数据集在这个镜头下,并显示它如何使一个新的视角对他们的时间模式,从凝聚力结构的作用,在网络上展开的过程中的特定时刻的研究感兴趣的网络的演变。

英文摘要:

Identifying the hidden organizational principles and relevant structures of networks representing complex physical systems is fundamental to understand their properties. To this aim, uncovering the structures involving a network's prominent nodes in a network is an effective approach. In temporal networks, the simultaneity of connections is crucial for temporally stable structures to arise. We thus propose here a novel measure to quantitatively investigate the tendency of well connected nodes to form simultaneous and stable structures in a temporal network. We refer to this tendency, when observed, as the "temporal rich club phenomenon". We illustrate the interest of this concept by analyzing diverse data sets under this lens, and showing how it enables a new perspective on their temporal patterns, from the role of cohesive structures in relation to processes unfolding on top of the network to the study of specific moments of interest in the evolution of the network.
