Systemic risk and network intervention
Luca Damonte, Giacomo Como, Fabio Fagnani
We consider a novel adversarial shock/protection problem for a class of network equilibria models emerging from a variety of different fields as continuous network games, productio…
Controlling network coordination games
Stephane Durand, Giacomo Como, Fabio Fagnani
We study a novel control problem in the context of network coordination games: the individuation of the smallest set of players capable of driving the system, globally, from one Na…
On stability of users equilibria in heterogeneous routing games
Leonardo Cianfanelli, Giacomo Como
The asymptotic behaviour of deterministic logit dynamics in heterogeneous routing games is analyzed. It is proved that in directed multigraphs with parallel routes, and in series c…
Stability and phase transitions of dynamical flow networks with finite capacities
Leonardo Massai, Giacomo Como, Fabio Fagnani
We study deterministic continuous-time lossy dynamical flow networks with constant exogenous demands, fixed routing, and finite flow and buffer capacities. In the considered model,…
Equilibria and Systemic Risk in Saturated Networks
Leonardo Massai, Giacomo Como, Fabio Fagnani
We undertake a fundamental study of network equilibria modeled as solutions of fixed point equations for monotone linear functions with saturation nonlinearities. The considered mo…
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…
