RT journal article T1 Perfect numerical semigroups A1 Moreno Frías, María Ángeles A1 Rosales, José Carlos A2 Matemáticas K1 Arf semigroup K1 embedding dimension K1 Frobenius number K1 genus K1 numerical semigroup K1 saturated semigroup AB A numerical semigroup is perfect if it does not have isolated gaps. In this paper we will order the perfectnumerical semigroups with a fixed multiplicity. This ordering allows us to give an algorithm procedure to obtain them.We also study the perfect monoid, which is a subset of N that can be expressed as an intersection of perfect numericalsemigroups, and we present the perfect monoid generated by a subset of N. We give an algorithm to calculate it. Westudy the perfect closure of a numerical semigroup, as well as the perfect numerical semigroup with maximal embeddingdimension, in particular Arf and saturated numerical semigroups.
