We study the set of numerical semigroups containing a given numerical semigroup. As an
application we prove characterizations of irreducible numerical semigroups that unify some …

Every numerical semigroup S admits a decomposition S= S1∩···∩ Sn with Si irreducible
(that is, Si is symmetric or pseudo-symmetric) for all i. We give lower and upper bounds for …

We study almost symmetric numerical semigroups and semigroup rings. We describe a
characteristic property of the minimal free resolution of the semigroup ring of an almost …

In this paper we present and study the numerical duplication of a numerical semigroup, a
construction that, starting with a numerical semigroup S and a semigroup ideal E⊆ S …
