A generalized Fan’s section theorem has proposed by replacing convexity assumptions with merely topological properties. A generalized reformulation of Browder’s fixed point theorem has derived. The minimax inequalities for vector-valued mapping in an ordered Banach space have established without the convexity and with convexity, respectively.
