Abstract
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.
