The multiples of a numerical semigroup

Ignacio Ojeda, José Carlos Rosales

Given two numerical semigroups $S$ and $T$ we say that $T$ is a multiple of $S$ if there exists an integer $d \in N ∖ {0}$ such that $S = \{x \in \mathbb{N} \mid…

The set of numerical semigroups of a given multiplicity and Frobenius number

M. B. Branco, I. Ojeda, J. C. Rosales

We study the structure of the family of numerical semigroups with fixed multiplicity and Frobenius number. We give an algorithmic method to compute all the semigroups in this famil…
