Alternative and minimax theorems beyond vector spaces

[摘要] The main results of this paper concern the minimax equality without algebraic structure of the underlying spaces. They include some classical minimax theorems as special cases and are independent of many other recent results of the same type. The proofs of our minimax theorems are based on some special alternative theorems established under some general connectedness conditions. (C) 2001 Elsevier Science.
