Abstract :
We apply the selection theorem for multivalued mappings with paraconvex values (rather than
various versions of KKM-principle) to prove several minimax theorems. In contrast with well-known
minimax theorems for coordinatewise semicontinuous functions, in our theorems finite intersections
of sublevel or uplevel sets can be nonempty and nonconnected.
