摘要: The new classes of LFc-correspondences and LFc -majorised correspondences without open lower sections is introduced. Some existence theorems of madximal elements of the LFc -correspondences and the LFc-majorized correspondences defined on noncompact set in topological vector spaces are obtained. As applications, some existence theorems of equilibrium points for one-person games, qualitative games and generalized games with the LFc -majorized correspondences devined on noncompact strategy sets in topological vector spaces are also given. These theorems improve and generalize several known results in recent literature.
