On a Network Centrality Maximization Game
Costanza Catalano, Maria Castaldo, Giacomo Como +1
We study a network formation game where players, identified with the nodes of a directed graph to be formed, choose where to wire their outgoing links in order to maximize thei…
Targeting interventions for displacement minimization in opinion dynamics
Luca Damonte, Giacomo Como, Fabio Fagnani
Social influence is largely recognized as a key factor in opinion formation processes. Recently, the role of external forces in inducing opinion displacement and polarization in so…
On a Centrality Maximization Game
Maria Castaldo, Costanza Catalano, Giacomo Como +1
The Bonacich centrality is a well-known measure of the relative importance of nodes in a network. This notion is, for example, at the core of Google's PageRank algorithm. In this p…
Threshold models of cascades in large-scale networks
Giacomo Como, Wilbert Samuel Rossi, Fabio Fagnani
The spread of new beliefs, behaviors, conventions, norms, and technologies in social and economic networks are often driven by cascading mechanisms, and so are contagion dynamics i…
Diffusion of innovation in large scale graphs
Fabio Fagnani, Lorenzo Zino
Will a new smartphone application diffuse deeply in the population or will it sink into oblivion soon? To predict this, we argue that common models of spread of innovations based o…
Opinion fluctuations and disagreement in social networks
Daron Acemoglu, Giacomo Como, Fabio Fagnani +1
We study a tractable opinion dynamics model that generates long-run disagreements and persistent opinion fluctuations. Our model involves an inhomogeneous stochastic gossip process…
