Species lifetime distribution for simple models of ecologies
S. Pigolotti, A. Flammini, M. Marsili +1
Interpretation of empirical results based on a taxa's lifetime distribution shows apparently conflicting results. Species' lifetime is reported to be exponentially distributed, whe…
Effect of degree correlations on the loop structure of scale-free networks
Ginestra Bianconi, Matteo Marsili
In this paper we study the impact of degree correlations in the subgraphs statistics of scale-free networks. In particular we consider loops: a simple case of network subgraphs whi…
Emergence of large cliques in random scale-free network
Ginestra Bianconi, Matteo Marsili
In a network cliques are fully connected subgraphs that reveal which are the tight communities present in it. Cliques of size c>3 are present in random Erdos and Renyi graphs only…
Dynamic instability in a phenomenological model of correlated assets
Giacomo Raffaelli, Matteo Marsili
We show that financial correlations exhibit a non-trivial dynamic behavior. We introduce a simple phenomenological model of a multi-asset financial market, which takes into account…
Critical threshold and dynamics of a general rumor model on complex networks
Maziar Nekovee, Yamir Moreno, Ginestra Bianconi +1
We derive mean-field equations that describe the dynamics of a general model of rumor spreading on complex networks, and use analytical and numerical solutions of these equations t…
Phase coexistence in a forecasting game
Philippe Curty, Matteo Marsili
Individual choices are either based on personal experience or on information provided by peers. The latter case, causes individuals to conform to the majority in their neighborhood…
On the rise and fall of networked societies
George C. M. A. Ehrhardt, Matteo Marsili, Fernando Vega-Redondo
We review recent results on the dynamics of social networks which suggest that the interplay between the network formation process and volatility may lead to the occurrence of disc…
Scale-free networks with an exponent less than two
Hamed Seyed-allaei, Ginestra Bianconi, Matteo Marsili
We study scale free simple graphs with an exponent of the degree distribution less than two. Generically one expects such extremely skewed networks -- which occur very frequent…
Emergence and resilience of social networks: a general theoretical framework
George C. M. A. Ehrhardt, Matteo Marsili, Fernando Vega-Redondo
We introduce and study a general model of social network formation and evolution based on the concept of preferential link formation between similar nodes and increased similarity…
On the interplay between fluctuations and efficiency in a model economy with heterogeneous adaptive consumers
Andrea De Martino, Matteo Marsili
We discuss the stationary states of a model economy in which heterogeneous adaptive consumers purchase commodity bundles repeatedly from sellers. The system undergoes a tra…
Loops of any size and Hamilton cycles in random scale-free networks
Ginestra Bianconi, Matteo Marsili
Loops are subgraphs responsible for the multiplicity of paths going from one to another generic node in a given network. In this paper we present an analytic approach for the evalu…
