Commutative Algebra 2021-03-10 v1 Combinatorics

Abstract

A numerical semigroup SS is an additive subsemigroup of the non-negative integers with finite complement, and the squarefree divisor complex of an element mSm \in S is a simplicial complex Δm\Delta_m that arises in the study of multigraded Betti numbers. We compute squarefree divisor complexes for certain classes numerical semigroups, and exhibit a new family of simplicial complexes that are occur as the squarefree divisor complex of some numerical semigroup element.
