Abstract :
Takao Fujimoto [Math. Program., 28(1984), 116-118] proved an extension of Tarski’s fixed point theorem for set-valued mappings with values in some types of posets. Our aim to prove an extension of this result for set valued mappings with values in a set equipped with a transitive binary relation.
