复杂网络中的“富俱乐部现象”是指网络中度较高的节点比度较低的节点具有更多的互联性。这种现象的存在可能表明了几个有趣的高级网络属性，例如对集线器故障的容忍度。在这里，作者研究了这种现象在几个现实世界网络的层次结构中的存在。他们的模拟表明，这种现象在网络中的存在或不存在并不意味着它在网络的连续层次中的存在或不存在，而且这种行为在某些情况下甚至是非单调的。(C)2007年，美国物理学会。
The "rich-club phenomenon" in complex networks is characterized when nodes of higher degree are more interconnected than nodes with lower degree. The presence of this phenomenon may indicate several interesting high-level network properties, such as tolerance to hub failures. Here, the authors investigate the existence of this phenomenon across the hierarchies of several real-world networks. Their simulations reveal that the presence or absence of this phenomenon in a network does not imply its presence or absence in the network's successive hierarchies, and that this behavior is even nonmonotonic in some cases.
