FIXED POINT PROPERTY AND COMPLETENESS OF ORDERED SETS
Abstract
In this paper, we characterize the existence of fixed points of a multivalued function by the existence of complete preorder on the given domain. Also we investigate relations between the completeness of a given order and the fixed point property of some multivalued functions.
