| Description | We iniciate here a systematic equational classification of semilattice-ordered semigroups. We start with various examples. Then we consider semilattice-ordered semigroups satisfying the identity x^r=x. Finally, we reduce the classification to finding certain operators on relatively free semigroups. |
