Abstract. In this paper, we obtain some
existence results for solutions of some generalized quasi-Ky Fan
inequalities and Nash equilibrium points for a game system in topological
semilattices. Our results are similar to the ones obtained by Luo under
some other conditions about continuity and convexity of vector set-valued
mappings.
