The study of 7r(K), the semiring of matrices which leave invariant the proper cone K, is continued in this paper. The definitions of Baer rings and Baer \* -rings are extended to semirings, at least in the case of 7r(K). Results that relate the concepts of right (left) annihilators, right (left) fac
## Abstract Let Ξ denote the semiring of isols. We characterize existential completeness for Nerode subsemirings of Ξ, by means of a purely isolβtheoretic βΞ£~1~ separation propertyβ. (A βconcreteβ characterization that is not Ξβtheoretic is well known: the existentially complete Nerode semirings ar
