随机相互作用粒子系统中的非均匀性效应
On the effect of heterogeneity in stochastic interacting-particle systems
摘要：
我们研究由异质单元组成的随机粒子系统。我们介绍了一个一般的框架，适合分析研究这种系统，并将其应用到两个特定的模型，在经济和流行病学的利益。我们表明，粒子的异质性可以增强或减少集体波动取决于系统，它是可能的，以推断的程度和形式的异质性分布在系统中，通过测量只有全球变量和它们的波动。
英文摘要：
We study stochastic particle systems made up of heterogeneous units. We introduce a general framework suitable to analytically study this kind of systems and apply it to two particular models of interest in economy and epidemiology. We show that particle heterogeneity can enhance or decrease the collective fluctuations depending on the system, and that it is possible to infer the degree and the form of the heterogeneity distribution in the system by measuring only global variables and their fluctuations.
