Regular equilibrium points of n-person games in normal form

Harsanyi introduced ~~gular equilibrium points in [3J and proved that for almost all noncooperative n-person games in normal form all equilibriUm points are regular. In this paper it is shown that regular equilibrium points are essential, quasi-strong, proper and perfect. Hence, for almost all games in normal form all equilibrium points are quasistrong,essential, proper and perfect.
