Abstract

Given mN,m\in \mathbb{N}, a numerical semigroup with multiplicity mm is called packed numerical semigroup if its minimal generating set is included in {m,m+1,,2m1}.\{m,m+1,\ldots, 2m-1\}. In this work, packed numerical semigroups are used to built the set of numerical semigroups with fixed multiplicity and embedding dimension, and to create a partition in this set. Moreover, Wilf's conjecture is checked in the tree associated to some packed numerical semigroups.
