On the uniqueness of Nash equilibrium in discontinuous ordinal and normal form games

Research Article


Our aim is to investigate the existence and uniqueness of Nash equilibrium in the general setting of ordinal games. Using a new property, called strict condition, we identify a class of discontinuous games where there exists a unique Nash equilibrium if and only if the single deviation property is satisfied.
