We introduce the notion of a δ-primary co-ideal of a commutative semiring R and study some of it properties. Here δ is a mapping that assigns to each co-ideal J a co-ideal δ(J)
of the same semiring. We investigate the relationship between the minimal prime co-ideals of R/I and δ(I)/I, when I is a δ-primary Q-co-ideal. We also prove that every identity summand
of R/I is contained in δ(I)/I and δ(I) contains all minimal prime co-ideals which contains I. |
