An intersection theorem for multivalued maps and applications
A new intersection theorem for multivalued maps is obtained. This new theorem requires the maps involved to satisfy a weaker compactness condition and generalizes known results. Applications of this new theorem are given to the existence of maximal and greatest elements for strict and weak relations and to minimax inequalities. (C) 2004 Elsevier Ltd. All rights reserved.
