Commutative partially ordered monoids
Abbreviation: CPoMon
Definition
A \emph{commutative partially ordered monoid} is a partially ordered monoid $\mathbf{A}=\langle A,\cdot,1,\le\rangle$ such that
$\cdot$ is \emph{commutative}: $xy=yx$
Remark: This is a template. If you know something about this class, click on the ``Edit text of this page'' link at the bottom and fill out this page.
It is not unusual to give several (equivalent) definitions. Ideally, one of the definitions would give an irredundant axiomatization that does not refer to other classes.
Morphisms
Let $\mathbf{A}$ and $\mathbf{B}$ be commutative partially ordered monoids. A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a orderpreserving homomorphism: $h(x \cdot y)=h(x) \cdot h(y)$, $h(1)=1$, and $x\le y\Longrightarrow h(x)\le h(y)$.
