Cycles structure and local ordering in complex networks
Guido Caldarelli, Romualdo Pastor-Satorras, Alessandro Vespignani
We study the properties of metrics aimed at the characterization of grid-like ordering in complex networks. These metrics are based on the global and local behavior of cycles of or…
Topology of correlation based minimal spanning trees in real and model markets
Giovanni Bonanno, Guido Caldarelli, Fabrizio Lillo +1
We present here a topological characterization of the minimal spanning tree that can be obtained by considering the price return correlations of stocks traded in a financial market…
Dynamic Fracture Model for Acoustic Emission
Manuela Minozzi, Guido Caldarelli, Luciano Pietronero +1
We study the acoustic emission produced by micro-cracks using a two-dimensional disordered lattice model of dynamic fracture, which allows to relate the acoustic response to the in…
Scale-free Networks without Growth or Preferential Attachment: Good get Richer
G. Caldarelli, A. Capocci, P. De Los Rios +1
A new mechanism leading to scale-free networks is proposed in this letter. It is shown that in many cases of interest, the connectivity power-law behavior is neither related to dyn…
Quantitative description and modeling of real networks
A. Capocci, G. Caldarelli, P. De Los Rios
In this letter we present data analysis and modeling of two particular cases of study in the field of growing networks. We analyze WWW data set and authorship collaboration network…
