Global topological synchronization of weighted simplicial complexes

Physical review. E, Год журнала: 2024, Номер 110(1)

Опубликована: Июль 31, 2024

Higher-order networks are able to capture the many-body interactions present in complex systems and unveil fundamental phenomena revealing rich interplay between topology, geometry, dynamics. Simplicial complexes higher-order that encode topology dynamics of systems. Specifically, simplicial can sustain topological signals, i.e., dynamical variables not only defined on nodes network but also their edges, triangles, so on. Topological signals undergo collective such as synchronization, however, some topologies global synchronization signals. Here we consider weighted complexes. We demonstrate globally synchronize complexes, even if they odd-dimensional, e.g., edge thus overcoming a limitation unweighted case. These results more advantageous for observing these than counterpart. In particular, two complexes: triangulated torus waffle. completely characterize spectral properties that, under suitable conditions weights, Our interpreted geometrically by showing, among other results, cases weights be associated with lengths sides curved simplices.

Turing patterns on discrete topologies: from networks to higher-order structures

Proceedings of the Royal Society A Mathematical Physical and Engineering Sciences, Год журнала: 2024, Номер 480(2302)

Опубликована: Ноя. 1, 2024

Nature is a blossoming of regular structures, signature self-organization the underlying microscopic interacting agents. Turing theory pattern formation one most studied mechanisms to address such phenomena and has been applied widespread gallery disciplines. himself used spatial discretization hosting support eventually deal with set ODEs. Such an idea contained seeds on discrete support, which fully acknowledged birth network science in early 2000s. This approach allows us tackle several settings not displaying trivial continuous embedding, as multiplex, temporal networks and, recently, higher-order structures. line research mostly confined within community, despite its inherent potential transcend conventional boundaries PDE-based patterns. Moreover, topology for novel dynamics be generated via universal formalism that can readily extended account The interplay between pave way further developments field.

Higher-order simplicial synchronization in coupled D -dimensional topological Kuramoto model

Physical Review Research, Год журнала: 2025, Номер 7(2)

Опубликована: Апрель 30, 2025

In this paper, we propose a D-dimensional topological Kuramoto model and investigate its synchronization on simplicial complexes. This extends the higher-order [] to D-dimensional sphere, where dynamics defined simplices of different dimensions are governed by D-dimensional model. By adopting an adaptive coupling, new phenomena phase transitions observed. Specifically, for nodal odd dimensions, double discontinuous transition is observed, whereas links, single occurs. Rigorous theoretical analysis reveals that originates from loss stability incoherent state saddle-node bifurcation in parameter space. Furthermore, D-dimensional links with D>2, unattainable because inability project onto adjacent dimensional simplices. Our findings provide insights into collective behaviors high-dimensional spaces, such as defense mechanisms or social insect swarms, mediated signal transmission environmental coupling.

Motifs-based link prediction for multiplexed networks

Chaos An Interdisciplinary Journal of Nonlinear Science, Год журнала: 2025, Номер 35(6)

Опубликована: Июнь 1, 2025

Link prediction on multiplexed networks has wide applications in various fields such as social and recommendation systems. Some algorithms have been proposed to solve link networks, which often rely single-layer node characteristics, inter-layer similarity, layer fusion. In this paper, we attempt address issue from the perspective of local structure that can be constructed by two nodes. We propose a motifs-based naïve Bayes model for multiplex considers number motif predictors role nodes composition different network layers. apply method multiple empirical results show our not only outperforms other existing but also high accuracy. addition, functions included can, indeed, help improve performance methods based solely motifs. The effectively leverages heterogeneity edges provides ideas more in-depth study networks.

Abstract Cascading failures caused by interdependencies make modern coupled systems extremely fragile to failures. In existing network robustness enhancing methods, maximizing interlayer degree-degree correlations has been proven be an effective way improve the of interdependent networks under random Here, we propose a portion nodes positively correlated strategy (PNC) correlating nodes, in which that are selected descending order degree, starting at cutoff value. Based on percolation theory, verify effectiveness PNC different networks. And find that, when with highest degree preferentially correlated, i.e. value takes maximum this achieves state-of-the-art optimization effect. particular, for scale-free power-law exponent γ satisfies 2 < γ 3 , theoretically demonstrate mode can maximize changing coupling state near 0 proportion nodes. For = 3, such turn into second-order phase transition collapse point. Finally, discuss relationship between optimized and common links real-world
