The set of distances in seminormal weakly Krull monoids

Abstract: Abstract. The set of distances of a monoid or of a domain is the set of all d ∈ N with the following property: there are irreducible elements. . · u k cannot be written as a product of l irreducible elements for any l with k < l < k + d. We show that the set of distances is an interval for certain seminormal weakly Krull monoids which include seminormal orders in holomorphy rings of global fields.

“…We mention two results valid for special classes of C-domains. There is a characterization of half-factoriality for orders in quadratic number fields in number theoretic terms ([10, Theorem 3.7.15]) and for a class of seminormal weakly Krull domains (including seminormal orders in number fields) in algebraic terms involving the v-class group and extension properties of prime divisorial ideals (see [11,Theorem 6.2] and [13]).…”

“…For every finite set C ⊂ N ≥2 , there is a finitely generated Krull monoid H 1 and, if max C ≥ 3, a numerical monoid H 2 such that Ca(H 1 ) = Ca(H 2 ) = C ( [36,10]). On the other hand, sets of distances and sets of catenary degrees are intervals for transfer Krull monoids over finite groups and for classes of seminormal weakly Krull monoids ( [21,18]). The main result (Theorem 5.1) of the present section states that the set of distances and the set of catenary degrees of B(D 2n ) are intervals.…”
