When is a numerical semigroup a quotient?

T Bogart, C O'NEILL, K Woods - Bulletin of the Australian …, 2024 - cambridge.org
A natural operation on numerical semigroups is taking a quotient by a positive integer. If, the
first known family of numerical semigroups that cannot be written as a k-quotient. We also …

On the genus of a quotient of a numerical semigroup

A Adeniran, S Butler, C Defant, Y Gao, PE Harris… - Semigroup Forum, 2019 - Springer
We find a relation between the genus of a quotient of a numerical semigroup S and the
genus of S itself. We use this identity to compute the genus of a quotient of S when S has …

The generating functions arise from the quotients of numerical semigroups

F Liu - arXiv preprint arXiv:2312.10889, 2023 - arxiv.org
In this paper, we propose a class generating functions $\textrm {RGF}(x) $ related to
Sylvester denumerant which arise from the quotients of numerical semigroups. Using …

Numerical semigroups via projections and via quotients

T Bogart, C O'Neill, K Woods - Discrete & Computational Geometry, 2024 - Springer
We examine two natural operations to create numerical semigroups. We say that a
numerical semigroup S is k-normalescent if it is the projection of the set of integer points in …

One half of almost symmetric numerical semigroups

F Strazzanti - Semigroup Forum, 2015 - Springer
Abstract Let S, TS, T be two numerical semigroups. We study when SS is one half of TT, with
TT almost symmetric. If we assume that the type of TT, t (T) t (T), is odd, then for any SS there …
