We study network games in which each player wishes to connect his source and sink, and the cost of each edge is shared among its users either equally (in Fair Connection Games--FCG's) or arbitrarily (in General Connection Games--GCG's). We study the existence and quality of strong equilibria...

A topology is efficient for network games if, for any game over it, every Nash equilibrium is socially optimal. It is well known that many topologies are not efficient for network games. We characterize efficient topologies in network games with a finite set of players, each wishing to transmit...
