On the computation of the Apéry set of numerical monoids and affine semigroups
Guadalupe Márquez-Campos, Ignacio Ojeda, José M. Tornero
A simple way of computing the Apéry set of a numerical semigroup (or monoid) with respect to a generator, using Groebner bases, is presented, together with a generalization for aff…

Almost symmetric numerical semigroups with high type
Pedro A. Garcia-Sanchez, Ignacio Ojeda
We establish a one-to-one correspondence between numerical semigroups of genus and almost symmetric numerical semigroups with Frobenius number and type , provided tha…

On pseudo-Frobenius elements of submonoids of
J. I. García-García, I. Ojeda, J. C. Rosales +1
In this paper we study those submonoids of which a non-trivial pseudo-Frobenius set. In the affine case, we prove that they are the affine semigroups whose associate…
