## Commutative ordered monoids

Abbreviation: **COMon**

### Definition

A \emph{commutative ordered monoid} is an (totally) 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 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 $x\le y\Longrightarrow h(x)\le h(y)$.
