论文摘要
渗透理论已被广泛用于研究复杂网络系统中的相变。它还成功地解释了各个领域的几种宏观现象。然而,现有的渗透理论框架将重点放在系统组成部分之间的直接相互作用上,而最近的经验观察表明,在许多系统中,例如生态和社交网络等许多系统中,间接相互作用很常见。在这里,我们提出了一个新的渗透框架,该框架解释了间接相互作用,该框架允许概括当前的理论主体,并了解网络系统组成部分对宏观行为的基本间接影响的作用。我们报告了一种丰富的现象学,其中可能的一阶,二阶或混合相变是可能的,具体取决于基板网络的链接分别是指向,无向导还是混合。我们还提出了一个分析框架,以表征所提出的诱导渗透,为通过间接相互作用进一步理解网络动态铺平了道路。
Percolation theory has been widely used to study phase transitions in complex networked systems. It has also successfully explained several macroscopic phenomena across different fields. Yet, the existent theoretical framework for percolation places the focus on the direct interactions among the system's components, while recent empirical observations have shown that indirect interactions are common in many systems like ecological and social networks, among others. Here, we propose a new percolation framework that accounts for indirect interactions, which allows to generalize the current theoretical body and understand the role of the underlying indirect influence of the components of a networked system on its macroscopic behavior. We report a rich phenomenology in which first-order, second-order or hybrid phase transitions are possible depending on whether the links of the substrate network are directed, undirected or a mix, respectively. We also present an analytical framework to characterize the proposed induced percolation, paving the way to further understand network dynamics with indirect interactions.
