Characterizing Twitter users behaviour during the Spanish Covid-19 first wave
Bernat Esquirol, Luce Prignano, Albert Díaz-Guilera +1
People use Online Social Media to make sense of crisis events. A pandemic crisis like the Covid-19 outbreak is a complex event, involving numerous aspects of the social life on mul…
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…
