Abstract: In this paper the notion of weak chain-completeness is introduced for pseudo-ordered sets as an extension of the notion of chain-completeness of posets (see ) and it is shown that every isotone map of a weakly chain-complete pseudo-ordered set into itself has a least fixed point.
Keywords: pseudo-ordered set, trellis, complete trellis, fixed point property, weak chain completeness
