Kehayopulu, Niovi On adjoining greatest element to ordered semigroups. (English) Zbl 0778.06013 Math. Jap. 38, No. 1, 61-66 (1993). Summary: As a continuation of our earlier paper [ibid. 36, 695-702 (1991; Zbl 0759.20018)], the adjunction of a greatest element to an ordered semigroup is actually an embedding problem. An adjunction is given by the second proof of the paper’s proposition. As a consequence, each ordered semigroup is embeddable in a regular (resp. intra-regular) poe-semigroup.
