In this paper we will order the perfect numerical 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 numerical semigroups, and we present the perfect monoid generated by a subset of N. We give an algorithm to calculate it. We study the perfect closure of a numerical semigroup, as well as the perfect numerical semigroup with maximal embedding dimension, in particular Arf and saturated numerical semigroups.}, publisher = {SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK}, keywords = {Arf semigroup}, keywords = {embedding dimension}, keywords = {Frobenius number}, keywords = {genus}, keywords = {numerical semigroup}, keywords = {saturated semigroup}, title = {Perfect numerical semigroups}, author = {Moreno Frías, María Ángeles and Rosales, José Carlos}, }
