Lin, Lai-Jiu; Cheng, Shih Feng Nash-type equilibrium theorems and competitive Nash-type equilibrium theorems. (English) Zbl 1103.91308 Comput. Math. Appl. 44, No. 10-11, 1369-1378 (2002). Summary: We consider two types of equilibrium problems. We study the constrained Nash-type equilibrium problems with multivalued payoff functions. We also study the competitive Nash-type equilibrium problems with multivalued payoff functions. In these two equilibrium problems, we want to find a strategy combination such that each player wishes to find a minimal loss from his multivalued payoff function. We use a fixed-point theorem of Park to prove the existence results of these two types of equilibrium problems.
