Dependency equilibria and their ev olutionary dynamics
\nNash equilibria are the fundamental n otion of game theory. They are characterized by the causal and hence (thou gh this is a fallacy) probabilistic independence of the choices of the pla yers. The notion of a dependency equilibrium (invented in 2003) is a natur al generalization of that notion\, which allows probabilistic (though not causal) dependence between those choices. (It differs from the notion of a correlated equilibrium well established since 1974.) Dependency equilibri a are well suited to explain cooperation among the players. For instance\, cooperation in the prisoners' dilemma and fair division in the ultimatum game are dependency equilibria. (These games have many dependency equilibr ia.) The talk will briefly explain this notion and emphasize that it is in deed meaningful. We have also studied various kinds of evolutionary dynami cs and the extent to which they converge to such dependency equilibria. Th e main purpose of the talk is to present some instructive examples of thos e dynamics.
