论文摘要

在复杂网络体系结构之上相互作用的动态系统中出现了各种集体动力学。沿着这一研究,时间网络已成为最有前途的网络平台之一。特别是,已经建立了具有空间移动代理的网络,以便能够建模许多实际实例。在本文中,我们根据其物理接近性相互作用的移动剂进行了动态结果。为此,我们特别强调代理商之间的竞争互动的影响,具体取决于其身体距离。我们特别假设彼此之间脱颖而出的代理之间的有吸引力的耦合,而我们对空间足够接近的代理采用排斥互动。通过此设置,我们考虑了两种类型的耦合配置,对称性打破和对称性的耦合。我们遇到集体动力学的变体,从同步,不均匀的小振荡到群集状态和极端事件,同时改变了吸引人和排斥的耦合强度。我们已经能够在耦合参数空间中映射所有这些动态行为。完全同步是在没有排斥耦合的情况下最需要的状态,我们为这种情况提供了一项分析研究,与数值结果非常吻合。

Diverse collective dynamics emerge in dynamical systems interacting on top of complex network architectures. Along this line of research, temporal network has come out to be one of the most promising network platforms to investigate. Especially, such network with spatially moving agents has been established to be capable of modelling a number of practical instances. In this paper, we examine the dynamical outcomes of moving agents interacting based upon their physical proximity. For this, we particularly emphasize on the impact of competing interactions among the agents depending on their physical distance. We specifically assume attractive coupling between agents which are staying apart from each other, whereas we adopt repulsive interaction for agents that are sufficiently close in space. With this set-up, we consider two types of coupling configurations, symmetry-breaking and symmetry-preserving couplings. We encounter variants of collective dynamics ranging from synchronization, inhomogeneous small oscillation to cluster state and extreme events while changing the attractive and repulsive coupling strengths. We have been able to map all these dynamical behaviors in the coupling parameter space. Complete synchronization being the most desired state in absence of repulsive coupling, we present an analytical study for this scenario that agrees well with the numerical results.
