Preferential Exchange: Strengthening Connections in Complex Networks
Guido Caldarelli, Fabrizio Coccetti, Paolo De Los Rios
Many social, technological and biological interactions involve network relationships whose outcome intimately depends on the structure of the network and on the strengths of the co…
On the Widespread Occurrence of the Inverse Square Distribution in Social Sciences and Taxonomy
Guido Caldarelli, Cecile Caretta Cartozo, Paolo De Los Rios +1
The widespread occurrence of an inverse square relation in the hierarchical distribution of sub-communities within communities (or sub-species within species) has been recently inv…
Number of h-cycles in the Internet at the Autonomous Systems level
Ginestra Bianconi, Guido Caldarelli, Andrea Capocci
We present here a study of the clustering and cycles present in the graph of Internet at the Autonomous Systems level. Even if the whole structure is changing with time, we present…
The scale-free topology of market investments
Diego Garlaschelli, Stefano Battiston, Maurizio Castri +2
We propose a network description of large market investments, where both stocks and shareholders are represented as vertices connected by weighted links corresponding to shareholdi…
Vertex Intrinsic Fitness: How to Produce Arbitrary Scale-Free Networks
Vito D. P. Servedio, Guido Caldarelli, Paolo Butta`
We study a recent model of random networks based on the presence of an intrinsic character of the vertices called fitness. The vertices fitnesses are drawn from a given probability…
Assortative model for social networks
Michele Catanzaro, Guido Caldarelli, Luciano Pietronero
In this paper we present a new version of a network growth model, generalized in order to describe the behavior of social networks. The case of study considered is the preprint arc…
