网络与状态协同进化中的时间尺度竞争导致分裂与重组转变
Time scale competition leading to fragmentation and recombination transitions in the coevolution of network and states
摘要：
在多状态交互主体模型中，研究了网络结构和节点状态的协同演化。该系统显示了两个过渡，网络重组和碎片化，从动态出现的时间尺度。重组转换将冻结配置（由断开连接的网络组件组成，这些组件的代理共享相同的状态）与活动配置（具有不断重新布线的一部分链路）分离。这种过渡的性质被解释为分析的最大特征时间。出现在两个吸收冻结相之间的碎裂转变是一种异常的有序-无序转变，由控制结构和状态动力学的时间尺度之间的交叉所控制。
英文摘要：
We study the co-evolution of network structure and node states in a model of multiple state interacting agents. The system displays two transitions, network recombination and fragmentation, governed by time scales that emerge from the dynamics. The recombination transition separates a frozen configuration, composed by disconnected network components whose agents share the same state, from an active configuration, with a fraction of links that are continuously being rewired. The nature of this transition is explained analytically as the maximum of a characteristic time. The fragmentation transition, that appears between two absorbing frozen phases, is an anomalous order-disorder transition, governed by a crossover between the time scales that control the structure and state dynamics.
