The convergence evolution in Europe from a complex networks perspective

Papadimitriou, Theophilos; Gkonkas, Periklēs; … - In: Journal of risk and financial management : JRFM 15 (2022) 10, pp. 1-14

The evolution of the convergence among the European countries, including both Eurozone as well as non-Eurozone economies, is investigated in this paper. To do so, we construct correlation-based networks and study them by employing the Threshold Weighted-Minimum Dominating Set (TW-MDS) algorithm...

Synchronization of Rössler oscillators on scale-free topologies

Yook, Soon-Hyung; Meyer-Ortmanns, Hildegard - In: Physica A: Statistical Mechanics and its Applications 371 (2006) 2, pp. 781-789

We study the synchronization of Rössler oscillators as prototypes of chaotic systems on scale-free complex networks. As … it turns out, the underlying topology crucially affects the global synchronization properties. In particular, we show … synchronization but also the type of loops. By considering Cayley trees modified by additional loops in different ways, we find out …

Concentric characterization and classification of complex network nodes: Application to an institutional collaboration network

Costa, Luciano da Fontoura; Rodrigues Tognetti, Marilza A. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 24, pp. 6201-6214

Differently from theoretical scale-free networks, most real networks present multi-scale behavior, with nodes structured in different types of functional groups and communities. While the majority of approaches for classification of nodes in a complex network has relied on local measurements of...

Statistics of epicenters in the Olami–Feder–Christensen model in two and three dimensions

Peixoto, Tiago P.; Prado, Carmen P.C. - In: Physica A: Statistical Mechanics and its Applications 342 (2004) 1, pp. 171-177

Recently, Abe and Suzuki pointed out that epicenters of earthquakes could be connected in order to generate a graph, with properties of a scale-free network. We have shown that the Olami–Feder–Christensen (OFC) model for the dynamics of earthquakes, defined both in square and cubic lattices,...

Jamming transition in air transportation networks

Lacasa, Lucas; Cea, Miguel; Zanin, Massimiliano - In: Physica A: Statistical Mechanics and its Applications 388 (2009) 18, pp. 3948-3954

In this work we present a model of an air transportation traffic system from the complex network modelling viewpoint. In the network, every node corresponds to a given airport, and two nodes are connected by means of flight routes. Each node is weighted according to its load capacity, and links...

Exploring the community structure of complex networks

Drago, Carlo - 2015 - This version 28 March 2015

Regarding complex networks, one of the most relevant problems is to understand and to explore community structure. In particular it is important to define the network organization and the functions associated to the different network partitions. In this context, the idea is to consider some new...
