Abstract: Abstract A semiring R is lattice-ordered if and only if it also has the structure of a lattice such that, for all a and b in R: (1) a + b = a ∨ b; and (2) ab ≤ a ∧ b, where partial order here is the one induced naturally by the lattice structure on R. If R, as a lattice, is distributive, then R is a distributive lattice-ordered semiring (DLO-semiring). Clearly any lattice-ordered semiring is a partially-ordered semiring in the sense of Chapter 18, with respect to the partial order induced by the lattice structure. (Note in passing that some authors replace (1) by a weaker condition; see, for example, [Ranga Rao, 1981].)
