Ambiguity in Game Theory
It is well-known that in the problem of decision under uncertainty, beliefs cannot always be represented by classical probabilities. Moreover, there is substantial evidence that this issue, (known as ambiguity), emerges even more clearly in game theory as the concept of Nash equilibrium has a specific source of uncertainty, known as strategic ambiguity. The increasing literature on ambiguous games looks at this subject from variegated perspectives and it has produced so many diversified results to the point that the connections among the different approaches have not been clarified yet in the literature. Aim of this project is to survey the main equilibrium concepts that have been defined for strategic form games in case of ambiguity and, then, to analyze connections among the different notions in a systematic way.
