In this work, we introduce the notion of almost-symmetry for generalized numerical
semigroups. In addition to the main properties occurring in this new class, we present …

The notion of an almost symmetric numerical semigroup was given by V. Barucci and R.
Fröberg in J. Algebra, 188, 418–442 (1997). We characterize almost symmetric numerical …

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 …

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 …

We give two algorithmic procedures to compute the whole set of almost symmetric numerical
semigroups with fixed Frobenius number and type, and the whole set of almost symmetric …

Abstract Let S, TS, T be two numerical semigroups. We study when SS is one half of TT, with
TT almost symmetric. If we assume that the type of TT, t (T) t (T), is odd, then for any SS there …

A generalized numerical semigroup is a submonoid of $\mathbb {N}^ d $ with finite
complement in it. In this work we study some properties of three different classes of …
