摘要
In this work, we first define the generalized 2 - g KKM mapping and the family 2 - g KKM (X, Y) in a hyperconvex metric space, and we get a fixed point theorem on this family without compact assumption. Next, we establish some variational inequalities and minimax inequalities for the family 2 - g KKM (X, Y) and the Φ-mapping. © 2008.
