Kunz languages for numerical semigroups are context sensitive
Manuel Delgado, Jaume Usó i Cubertorer
There is a one-to-one and onto correspondence between the class of numerical semigroups of depth , where is an integer, and a certain language over the alphabet $\{1,\ldots,…
Trimming the numerical semigroups tree to probe Wilf's conjecture to higher genus
Manuel Delgado
This paper aims to contribute to validate, for numerical semigroups of reasonably large genus, the so-called Conjecture of Wilf. There is no counter-example for the conjecture amon…
Algorithms for Generalized Numerical Semigroups
Carmelo Cisto, Manuel Delgado, Pedro A. García-Sánchez
We provide algorithms for performing computations in generalized numerical semigroups, that is, submonoids of with finite complement in . These sem…
Conjecture of Wilf: a survey
Manuel Delgado
This paper intends to survey the vast literature devoted to a problem posed by Wilf in 1978 which, despite the attention it attracted, remains unsolved. As it frequently happens wi…
On a question of Eliahou and a conjecture of Wilf
Manuel Delgado
To a numerical semigroup , Eliahou associated a number and proved that numerical semigroups for which the associated number is non negative satisfy Wilf's conjecture. The…
numericalsgps, a GAP package for numerical semigroups
Manuel Delgado, Pedro A. García Sánchez
The package numericalsgps performs computations with and for numerical semigroups. Recently also affine semigroups are admitted as objects for calculations. This manuscript is a su…
On the weight hierarchy of codes coming from semigroups with two generators
M. Delgado, J. I. Farrán, P. A. García-Sánchez +1
The weight hierarchy of one-point algebraic geometry codes can be estimated by means of the generalized order bounds, which are described in terms of a certain Weierstrass semigrou…
Numerical semigroups problem list
Manuel Delgado, Pedro A. Garcia-Sanchez, José C. Rosales
We propose a list of open problems in numerical semigroups.
Rees quotients of numerical semigroups
Manuel Delgado, Vítor H. Fernandes
We introduce a class of finite semigroups obtained by considering Rees quotients of numerical semigroups. Several natural questions concerning this class, as well as particular sub…
On the generalized Feng-Rao numbers of numerical semigroups generated by intervals
M. Delgado, J. I. Farrán, P. A. García-Sánchez +1
We give some general results concerning the computation of the generalized Feng-Rao numbers of numerical semigroups. In the case of a numerical semigroup generated by an interval,…
