Quasi-Residuated Mappings and Baer Assemblies.
Abstract
We consider, for a given ordered set E with minimum element O, the semigroup Q of O-preserving isotone mappings on E and examine necessary and sufficient conditions under which an element in which point f belongs to set Q is such that the left (resp. right) annihilator of f in Q is a principal left (resp. right) ideal of Q generated by a particular type of idempotent. The results obtained lead us to introduce the concept of a Baer assembly which we use to extend to the case of a semilattice the Baer semigroup coordinatisation theory of lattices. We also derive a coordinatisation of particular types of semilattice. (Author)
