On arithmetical numerical monoids with some generators omitted
Sung Hyup Lee, Christopher O'Neill, Brandon Van Over
Numerical monoids (cofinite, additive submonoids of the non-negative integers) arise frequently in additive combinatorics, and have recently been studied in the context of factoriz…
Random numerical semigroups and a simplicial complex of irreducible semigroups
Jesus De Loera, Christopher O'Neill, Dane Wilburne
We examine properties of random numerical semigroups under a probabilistic model inspired by the Erdos-Renyi model for random graphs. We provide a threshold function for cofinitene…
Apéry sets of shifted numerical monoids
Christopher O'Neill, Roberto Pelayo
A numerical monoid is an additive submonoid of the non-negative integers. Given a numerical monoid , consider the family of "shifted" monoids obtained by adding to eac…
Some algebraic aspects of mesoprimary decomposition
Laura Felicia Matusevich, Christopher O'Neill
Recent results of Kahle and Miller give a method of constructing primary decompositions of binomial ideals by first constructing "mesoprimary decompositions" determined by their un…
Realizable sets of catenary degrees of numerical monoids
Christopher O'Neill, Roberto Pelayo
The catenary degree is an invariant that measures the distance between factorizations of elements within an atomic monoid. In this paper, we classify which finite subsets of $\math…
The Elasticity of Puiseux Monoids
Felix Gotti, Christopher O'Neill
Let be an atomic monoid and let be a non-unit element of . The elasticity of , denoted by , is the ratio of its largest factorization length to its shortest fac…
Minimal presentations of shifted numerical monoids
Rebecca Conaway, Felix Gotti, Jesse Horton +4
A numerical monoid is an additive submonoid of the non-negative integers. Given a numerical monoid , consider the family of "shifted" monoids obtained by adding to eac…
