Generalized monotone bifunctions and equilibrium problems. (English) Zbl 0903.49006
An equilibrium problem is studied in this paper which includes, e.g., the variational inequality as a special case. The existence of a solution for the equilibrium problem is derived using the quasimonotone condition. Moreover, characterizations, such as convexity and compactness, of the solution set for the equilibrium problem are also given.
