Additive submonoids of $\mathbb{Q}_{\ge 0}$, also known as Puiseux monoids, are not unique factorization monoids (UFMs) in general. Indeed, the only unique factorization Puiseux monoids are those generated by one element. However, even if a Puiseux monoid is not a UFM, it may contain nonzero elements having exactly one factorization. We call such elements molecules. Molecules were first investigated by W. Narkiewicz in the context of algebraic number theory. More recently, F. Gotti and the…

Factorizations in reciprocal Puiseux monoids
A Puiseux monoid is an additive submonoid of the real line consisting of rationals. We say that a Puiseux monoid is reciprocal if it can be generated by the reciprocals of the terms of a strictly

When Is a Puiseux Monoid Atomic?
TLDR
This work surveys some of the most relevant aspects related to the atomicity of Puiseux monoids and provides characterizations of when M is finitely generated, factorial, half-factorial, other-half- Factorial, Prüfer, seminormal, root-closed, and completely integrally closed.

A Puiseux monoid is an additive submonoid of the nonnegative cone of $\mathbb{Q}$. Puiseux monoids exhibit, in general, a complex atomic structure. For instance, although various techniques have been

In this paper, we construct three families of semigroup algebras using Puiseux monoids, recently-studied additive submonoids of $\mathbb{Q}$. The first family consists of semigroup algebras of
