Computation of numerical semigroups by means of seeds
Bras Amorós, Maria; Fernández González, Julio (2018-09-01)
Article
Accés obertFor the elements of a numerical semigroup which are larger than the Frobenius number, we introduce the definition of seed by broadening the notion of generator. This new concept allows us to explore the semigroup tree in ... -
On the existence of combinatorial configurations
Bras Amorós, Maria; Stokes, Klara (Iniciativa Digital Politècnica, 2011)
Text en actes de congrés
Accés obertA (v, b, r, k) combinatorial configuration can be defined as a connected, (r, k)-biregular bipartite graph with v vertices on one side and b vertices on the other and with no cycle of length 4. Combinatorial configurations ... -
The right-generators descendant of a numerical semigroup
Bras Amorós, Maria; Fernández González, Julio (2020-01-01)
Article
Accés obertFor a numerical semigroup, we encode the set of primitive elements that are larger than its Frobenius number and show how to produce in a fast way the corresponding sets for its children in the semigroup tree. This allows ...
