Modeling Public Opinion Dynamics: The Spiral of silence in clustered homophilic networks
Juan Castillo, Emanuele Cozzo
Public discourse emerges from the interplay between individuals' willingness to voice their opinions and the structural features of the social networks in which they are embedded.…
Layer degradation triggers an abrupt structural transition in multiplex networks
Emanuele Cozzo, Guilherme Ferraz de Arruda, Francisco A. Rodrigues +1
Network robustness is a central point in network science, both from a theoretical and a practical point of view. In this paper, we show that layer degradation, understood as the co…
A polynomial eigenvalue approach for multiplex networks
Guilherme Ferraz de Arruda, Emanuele Cozzo, Francisco A. Rodrigues +1
We explore the block nature of the matrix representation of multiplex networks, introducing a new formalism to deal with its spectral properties as a function of the inter-layer co…
A complex network framework to model cognition: unveiling correlation structures from connectivity
Gemma Rosell-Tarragó, Emanuele Cozzo, Albert Díaz-Guilera
Several approaches to cognition and intelligence research rely on statistics-based models testing, namely factor analysis. In the present work we exploit the emerging dynamical sys…
Levy random walks on multiplex networks
Quantong Guo, Emanuele Cozzo, Zhiming Zheng +1
Random walks constitute a fundamental mechanism for many dynamics taking place on complex networks. Besides, as a more realistic description of our society, multiplex networks have…
On degree-degree correlations in multilayer networks
Guilherme Ferraz de Arruda, Emanuele Cozzo, Yamir Moreno +1
We propose a generalization of the concept of assortativity based on the tensorial representation of multilayer networks, covering the definitions given in terms of Pearson and Spe…
