The notion of an admissible semigroup is introduced. This is an (additive) semigroup on which a multiplication turning it into a multiplicatively idempotent semiring with identity can be defined. Admissible semilattices are studied. In particular, countable admissible and inadmissible “universal” semilattices are constructed, into which all finite semilattices are isomorphically embedded.
Keywords:
semilattice, idempotent semiring, admissible semilattice.
