Let $\Delta$ be a numerical semigroup. In this work we show that $\mathcal{J}(\Delta) =\{I\cup\nobreak\{0\} I is an ideal of \Delta\}$ is a distributive lattice, which in addition is a Frobenius restricted variety. We give an algorithm which allows u

In this work, we show that if F is a positive integer, then Sat(F)={S∣S is a saturated numerical semigroup with Frobenius number F} is a covariety. As a consequence, we present two algorithms: one that computes Sat(F), and another which computes al

In this work, we will introduce the concept of ratio-covariety, as a family R of numerical semigroups that has a minimum, denoted by min(R), is closed under intersection, and if S∈R and S≠min(R), then S\{r(S)}∈R, where r(S) denotes the ratio of
