1. The document discusses several equilibrium concepts beyond Nash equilibrium including correlated equilibrium, evolutionary equilibrium, and Bayesian Nash equilibrium. 2. A correlated equilibrium is a generalization of Nash equilibrium where players' actions may be correlated based on a common signal, rather than being independent. 3. An evolutionary stable strategy is a strategy that, if adopted by a population, cannot be invaded by any alternative strategy. It is a refinement of Nash equilibrium from an evolutionary perspective.
