标题： Interconnecting bilayer networks

摘要： 一个典型的复杂系统应该由超网络或网络的网络来描述，在其中网络与其他一些网络相耦合。 作为理解这种更系统化层面的复杂系统的第一个步骤，科学家们研究了相互依赖的多层网络。 在本文中，我们引入了一种新的相互依赖的多层网络，即互联网络，其中的组件网络通过共享一些公共节点彼此耦合。 基于实证研究，我们揭示了这种互联网络的一个共同特征，即互联节点的平均拓扑差异较小的网络倾向于共享更多的节点。 提出了一种非常简单的节点共享机制，以解析地解释互联网络的观察到的特征。 显示英文摘要

摘要： A typical complex system should be described by a supernetwork or a network of networks, in which the networks are coupled to some other networks. As the first step to understanding the complex systems on such more systematic level, scientists studied interdependent multilayer networks. In this letter, we introduce a new kind of interdependent multilayer networks, i.e., interconnecting networks, for which the component networks are coupled each other by sharing some common nodes. Based on the empirical investigations, we revealed a common feature of such interconnecting networks, namely, the networks with smaller averaged topological differences of the interconnecting nodes tend to share more nodes. A very simple node sharing mechanism is proposed to analytically explain the observed feature of the interconnecting networks.
