    • An algorithm to compute the primitive elements of an embedding dimension three numerical semigroups 

      Aguiló Gost, Francisco de Asis L.; García Sánchez, Pedro A.; Llena, David (2014)
      Article
      Open Access
      We give an algorithm to compute the set of primitive elements for an embedding dimension three numerical semigroups. We show how we use this procedure in the study of the construction of L-shapes and the tame degree of the ...
    • Computing denumerants in numerical 3-semigroups 

      Aguiló Gost, Francisco de Asis L.; Llena, David (2018)
      Article
      Open Access
      As far as we know, usual computer algebra packages can not compute denumerants for almost medium (about a hundred digits) or almost medium-large (about a thousand digits) input data in a reasonably time cost on an ordinary ...
    • Denumerants of 3-numerical semigroups 

      Aguiló Gost, Francisco de Asis L.; García Sánchez, Pedro A.; Llena, David (2014)
      Article
      Open Access
      Denumerants of numerical semigroups are known to be difficult to obtain, even with small embedding dimension of the semigroups. In this work we give some results on denumerants of 3-semigroups S=<a,b,c>S=<a,b,c>. Closed ...
    • On the number of L-shapes in embedding dimension four numerical semigroups 

      Aguiló Gost, Francisco de Asis L.; García Sánchez, Pedro A.; Llena, David (2015-12-06)
      Article
      Open Access
      Minimum distance diagrams, also known as L-shapes, have been used to study some properties related to weighted Cayley digraphs of degree two and embedding dimension three numerical semigroups. In this particular case, it ...
