真实多层网络的隐藏多尺度组织与鲁棒性

Hidden multiscale organization and robustness of real multiplex networks

Gangmin Son, Meesoon Ha, Hawoong Jeong

AI总结:

本文通过隐藏几何框架在真实多层网络中发现名为clan的介观组织,揭示其与相互渗透及鲁棒性的关系,表明clan使系统脆弱但不易完全破碎,并确认多尺度性与整体鲁棒性相关。

摘要:

隐藏几何使得能够在不同尺度上研究复杂网络。将该框架扩展到多层网络,我们在真实多层系统中发现了一种新型的介观组织,命名为clan,即一组在层间保持其局部几何排列的节点。此外,我们揭示了clan结构的展开与针对定向攻击的相互渗透之间的密切关系,导致clan具有矛盾的角色:使系统脆弱但更不易完全破碎。最后,我们确认了几何组织的多尺度性质与整体鲁棒性之间的相关性。我们的发现扩展了隐藏几何在网络功能中的重要性,同时也强调了评估和控制多层系统灾难性失效的潜在陷阱。

英文摘要:

Hidden geometry enables the investigation of complex networks at different scales. Extending this framework to multiplex networks, we uncover a novel kind of mesoscopic organization in real multiplex systems, named $\textit{clan}$, a group of nodes that preserve their local geometric arrangement across layers. Furthermore, we reveal the intimate relationship between the unfolding of clan structure and mutual percolation against targeted attacks, leading to an ambivalent role of clans: making a system fragile yet less prone to complete shattering. Finally, we confirm the correlation between the multiscale nature of geometric organization and the overall robustness. Our findings expand the significance of hidden geometry in network function, while also highlighting potential pitfalls in evaluating and controlling catastrophic failure of multiplex systems.
