Existence theorems of Nash equilibria for non-cooperative $$n$$-person games. (English) Zbl 0837.90126
Summary: We first obtain existence theorems of Nash equilibria for non-cooperative $$n$$-person games which generalize a corresponding result of Nikaido and Isoda (1955). As applications, we give two new existence theorems of $$\varepsilon$$-equilibrium points which generalize that of Tijs (1981). Finally, a saddle point theorem of Komiya (1986) is deduced from one of our existence theorems of $$\varepsilon$$-equilibrium points.
