Correlated equilibria are a generalization of Nash equilibria. Existence of a correlated equilibrium is guaranteed due to existence of a Nash equilibrium. In this talk I will present a result of Germano & Lugosi(2007) that shows every finite normal form game possesses a sparsely supported correlated equilibrium.
