We examine the formation of networks among a set of players whose payoffs depend on the structure of the network. We … links. We characterize the networks that are supported under these variations and show how each of the above aspects is …

This paper studies fictitious play in networks of noncooperative two-player games. We show that continuous …-play property. As an extension, we consider networks in which each bilateral game is strategically zero-sum, a weighted potential …, which entails a generalization of Robinson's theorem to arbitrary zero-sum networks. Applications include security games …
