Commutative residuated lattice-ordered semigroups
Abbreviation: CRLSgrp
Definition
A \emph{commutative residuated lattice-ordered semigroup} is a residuated lattice-ordered semigroup $\mathbf{A}=\langle A, \vee, \wedge, \cdot, \to\rangle$ 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 residuated lattice-ordered semigroups. A morphism from $\mathbf{A}$ to $\mathbf{B}$ is a function $h:A\rightarrow B$ that is a homomorphism: $h(x \vee y)=h(x) \vee h(y)$, $h(x \wedge y)=h(x) \wedge h(y)$, $h(x \cdot y)=h(x) \cdot h(y)$, and $h(x \to y)=h(x) \to h(y)$.
