AI总结:

本文提出通用形式化框架研究时序网络上的非马尔可夫接触与传播过程,证明在特定条件下其等价于静态网络上的马尔可夫动力学,且该结论不依赖网络拓扑。

摘要:

许多实证研究已揭示,与人类活动相关的接触发生是非马尔可夫时间过程,其事件间隔时间分布呈重尾特征。此外,越来越多的实证证据表明感染率和恢复率是随时间变化的。然而,我们缺乏一个综合分析时序网络上非马尔可夫接触与传播过程的框架。本文提出一种通用形式化方法,用于研究非马尔可夫时序网络上的非马尔可夫动力学。我们发现,在特定条件下,时序网络上的非马尔可夫动力学等价于静态网络上的马尔可夫动力学。有趣的是,这一结果与底层网络拓扑结构无关。

英文摘要:

Many empirical studies have revealed that the occurrences of contacts associated with human activities are non-Markovian temporal processes with a heavy tailed inter-event time distribution. Besides, there has been increasing empirical evidence that the infection and recovery rates are time-dependent. However, we lack a comprehensive framework to analyze and understand non-Markovian contact and spreading processes on temporal networks. In this paper, we propose a general formalism to study non-Markovian dynamics on non-Markovian temporal networks. We find that, under certain conditions, non-Markovian dynamics on temporal networks are equivalent to Markovian dynamics on static networks. Interestingly, this result is independent of the underlying network topology.
