On degree-degree correlations in multilayer networks
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 Spearman coefficients. Our approach can also be applied to weighted networks and provides information about correlations considering pairs of layers. By analyzing the multilayer representation of the airport transportati...

متن کاملDegree-degree correlations in directed networks with heavy-tailed degrees
In network theory, Pearson’s correlation coefficients are most commonly used to measure the degree assortativity of a network. We investigate the behavior of these coefficients in the setting of directed networks with heavy-tailed degree sequences. We prove that for graphs where the inand out-degree sequences satisfy a power law, Pearson’s correlation coefficients converge to a non-negative num...
متن کاملGenerating random networks with given degree-degree correlations and degree-dependent clustering.
Random networks are widely used to model complex networks and research their properties. In order to get a good approximation of complex networks encountered in various disciplines of science, the ability to tune various statistical properties of random networks is very important. In this Brief Report we present an algorithm which is able to construct arbitrarily degree-degree correlated networ...
متن کاملFoundations for Cooperation in the Prisoners ’ Dilemma
We provide axiomatic foundations for a simple model of play in prisoners’ dilemma games. The model accommodates cooperation and suggests that players behave as if their expectations about their opponents’ behavior vary with their own choice. We refer to this nonstandard updating as magical thinking. The degree to which players exhibit magical thinking may be heterogeneous in the population and ...
