Diverse higher-order structures, foundational for supporting a network’s “meta-functions”, play vital role in structure, functionality, and the emergence of complex dynamics. Nevertheless, problem dismantling them has been consistently overlooked. In this paper, we introduce concept with objective disrupting not only network connectivity but also eradicating all structures each branch, thereby ensuring thorough functional paralysis. Given diversity unknown specifics identifying targeting individually is practical or even feasible. Fortunately, their close association k-cores arises from internal high connectivity. Thus, transform structure measurement into measurements on corresponding orders. Furthermore, propose Belief Propagation-guided Higher-order Dismantling (BPHD) algorithm, minimizing costs while achieving maximal disruption to ultimately converting forest. BPHD exhibits explosive vulnerability counterintuitively showcasing decreasing increasing structural complexity. Our findings offer novel approach malignant networks, emphasizing substantial challenges inherent safeguarding against such malicious attacks.

Searching for key nodes and edges in a network is long-standing problem. Recently cycle structure has received more attention. Is it possible to propose ranking algorithm importance? We address the problem of identifying cycles network. First, we provide concrete definition importance-in terms Fiedler value (the second smallest Laplacian eigenvalue). Key are those that contribute most substantially dynamical behavior Second, by comparing sensitivity different cycles, neat index provided. Numerical examples given show effectiveness this method.

Abstract Empirical networks exhibit significant heterogeneity in node connections, resulting a few vertices playing critical roles various scenarios, including decision-making, viral marketing, and population immunization. Thus, identifying key is fundamental research problem Network Science. In this paper, we introduce vertex entanglement (VE), an entanglement-based metric capable of quantifying the perturbations caused by individual on spectral entropy, residing at intersection quantum information network science. Our analytical analysis reveals that VE closely related to robustness transmission ability. As application, offers approach challenging optimal dismantling, empirical experiments demonstrate its superiority over state-of-the-art algorithms. Furthermore, also contributes diagnosis autism spectrum disorder (ASD), with distinctions hub disruption indices based between ASD typical controls, promising diagnostic role for assessment.

Abstract Networks in nature have complex interactions among agents. One significant phenomenon induced by is synchronization of coupled agents, and the interactive network topology can be tuned to optimize synchronization. Previous studies showed that optimized conventional with pairwise favors a homogeneous degree distribution nodes for undirected interactions, always structurally asymmetric directed interactions. However, optimal control on prevailing higher-order less explored. Here, considering hypergraph Kuramoto model 2-hyperlink we find synchronizability may distinct properties. For networks simulated annealing tend become nodes’ generalized degree. We further rigorously demonstrate structural symmetry preserved optimally synchronizable The results suggest controlling leads phenomena beyond
