(last updated on 2025/06/14)Abstract:
Numerical semigroups with multiplicity m are parametrized by integer points in a polyhedral cone Cm , according to Kunz. For the toric ideal of any such semigroup, the main result here constructs a free resolution whose overall structure is identical for all semigroups parametrized by the relative interior of a fixed face of Cm . The matrix entries of this resolution are monomials whose exponents are parametrized by the coordinates of the corresponding point in Cm , and minimality of the resolution is achieved when the semigroup is of maximal embedding dimension, which is the case when it is parametrized by the interior of Cm itself.
