Apéry sets of shifted numerical monoids
A numerical monoid is an additive submonoid of the non-negative integers. Given a numerical monoid \(S\), consider the family of "shifted" monoids \(M_n\) obtained by adding \(n\) to each generator of \(S\). In this paper, we characterize the Apéry set of \(M_n\) in terms of the Apéry set...

Summary: | A numerical monoid is an additive submonoid of the non-negative integers. Given a numerical monoid \(S\), consider the family of "shifted" monoids \(M_n\) obtained by adding \(n\) to each generator of \(S\). In this paper, we characterize the Apéry set of \(M_n\) in terms of the Apéry set of the base monoid \(S\) when \(n\) is sufficiently large. We give a highly efficient algorithm for computing the Apéry set of \(M_n\) in this case, and prove that several numerical monoid invariants, such as the genus and Frobenius number, are eventually quasipolynomial as a function of \(n\). |
