Abstract
We discuss the conditions under which a population of anomalously diffusing individuals can be characterized by demographic fluctuations that are anomalously scaling themselves. Two examples are provided in the case of individuals migrating by Gaussian diffusion, and by a sequence of Lévy flights.
摘要
我们讨论了在何种条件下，一群呈现异常扩散的个体能够由其自身也呈现异常标度的人口统计学波动来表征。对于通过高斯扩散迁移的个体以及通过一系列 Lévy 飞行迁移的个体这两种情况，我们给出了示例。
