Towards a Better Understanding of the Semigroup Tree
Maria Bras-Amoros, Stanislav Bulygin
In this paper we elaborate on the structure of the semigroup tree and the regularities on the number of descendants of each node observed earlier. These regularites admit two diffe…

Bounds on the Number of Numerical Semigroups of a Given Genus
Maria Bras-Amoros
Combinatorics on multisets is used to deduce new upper and lower bounds on the number of numerical semigroups of each given genus, significantly improving existing ones. In particu…

Representation of Numerical Semigroups by Dyck Paths
Maria Bras-Amorós, Anna de Mier
We introduce square diagrams that represent numerical semigroups and we obtain an injection from the set of numerical semigroups into the set of Dyck paths.
