【Abstract】 In this paper,by applying the properties of better admissible mappings, some new collectively fixed point theorems for a family of set-valued mappings defined on the product space of noncompact G-convex spaces are proved. Some existence theorems of maximal element are given in G-convex spaces. As applications some equlibrium existence theorems of economies are obtained.These theorems improve, unify and generalize many important known results in the recent literature.更多还原
