无标度网络上的反常集合种群动力学

Anomalous metapopulation dynamics on scale-free networks

Sergei Fedotov, Helena Stage

摘要:

我们的模型运输的个人在一个异构的无标度网络中,一些弱连接的节点表现出重尾停留时间。使用经验法则公理的累积惯性和分数分析,我们表明,“异常累积惯性”压倒高度连接的节点在吸引网络的个人。这从根本上挑战了个体倾向于在高阶节点中积累的经典结果。导出的停留时间分布具有非平凡的U形,我们在人类居住和就业时间的经验遇到。

英文摘要:

We model transport of individuals across a heterogeneous scale-free network where a few weakly connected nodes exhibit heavy-tailed residence times. Using the empirical law Axiom of Cumulative Inertia and fractional analysis we show that `anomalous cumulative inertia' overpowers highly connected nodes in attracting network individuals. This fundamentally challenges the classical result that individuals tend to accumulate in high-order nodes. The derived residence time distribution has a non-trivial U-shape which we encounter empirically across human residence and employment times.
