A numerical semigroup is a subset of the set N of nonnegative integers that is closed under
addition, contains 0 and whose complement in N is finite. The smallest positive integer …

We study star operations on Kunz domains, a class of analyti-cally irreducible, residually
rational domains associated to pseudo-symmetricnumerical semigroups, and we use them …

We introduce an order on the set of nondivisorial ideals of a numerical semigroup $ S $, and
link antichains of this order with the star operations on $ S $; subsequently, we use this order …

We study the cardinality of the set Star (S) of star operations on a numerical semigroup S; in
particular, we study ways to estimate Star (S) and to bound the number of nonsymmetric …

The set 𝒢 0 (S) of the classes of nondivisorial ideals of a numerical semigroup S can be
endowed with a natural partial order induced by the set of star operations on S. We study …

A closure operation is a map c from a partially ordered set P to itself that veri es three
properties: it is extensive (that is, xc (x) for every x 2 P), order-preserving (if xy, then c (x) c …
