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…
Uniqueness of Limit Cycles for Quadratic Vector Fields
José Luis Bravo, Manuel Fernández, Ignacio Ojeda +1
This article deals with the study of the number of limit cycles surrounding a critical point of a quadratic planar vector field, which, in normal form, can be written as $x'= a_1 x…
Critical binomial ideals of Norhtcott type
P. A. García-Sánchez, D. Llena, I. Ojeda
In this paper, we study a family of binomial ideals defining monomial curves in the dimensional affine space determined by hypersurfaces of the form $x_i^{c_i} - x_1^{u_{i1…
