User Value in Modern Payment Platforms: A Graph Approach
Laura Arditti, Martino Trevisan, Luca Vassio +2
Payment platforms have significantly evolved in recent years to keep pace with the proliferation of online and cashless payments. These platforms are increasingly aligned with onli…
Equilibria and learning dynamics in mixed network coordination/anti-coordination games
Laura Arditti, Giacomo Como, Fabio Fagnani +1
Whilst network coordination games and network anti-coordination games have received a considerable amount of attention in the literature, network games with coexisting coordinating…
BMO spaces on weighted homogeneous trees
Laura Arditti, Anita Tabacco, Maria Vallarino
We consider an infinite homogeneous tree endowed with the usual metric defined on graphs and a weighted measure . The metric measure space is…
Robustness of Nash Equilibria in Network Games
Laura Arditti, Giacomo Como, Fabio Fagnani +1
We analyze the robustness of (pure strategy) Nash equilibria for network games against perturbations of the players' utility functions. We first derive a simple characterization of…
Graphical Games and Decomposition
Laura Arditti, Giacomo Como, Fabio Fagnani
We consider graphical games as introduced by Kearns et al. (2001). First we analyse the interaction of graphicality with a notion of strategic equivalence of games, providing a min…
Separable games
Laura Arditti, Giacomo Como, Fabio Fagnani
We present the notion of separable game with respect to a forward directed hypergraph (FDH-graph), which refines and generalizes that of graphical game. First, we show that there e…
