| Abstract: | In this paper, new generalized metric S-KKM theorems are obtained when S is a set-valued mapping in noncompact hyperconvex spaces . As applications, a Ky Fan matching theorem for transfer open covers, a Fan- Browder coincidence theorem and maximal element theorem are established. Finally, equilibrium existence theorems for qualitative games and abstract economies in noncompact hyperconvex spaces are yielded. |
