We generalize two known results of R.E. Smithson [Fixed points in partially ordered sets, Pacific J. Math. 45 (1) (1973) 363-367] for commutative multifunctions in posets. The main result proves the existence of the minimum common fixed point under suitable conditions.

Abstract
We generalize two known results of R.E. Smithson [Fixed points in partially ordered sets, Pacific J. Math. 45 (1) (1973) 363-367] for commutative multifunctions in posets. The main result proves the existence of the minimum common fixed point under suitable conditions.File in questo prodotto:
