Equivalence \`a la Mundici for commutative lattice-ordered monoids

We provide a generalization of Mundici’s equivalence between unital Abelian lattice-ordered groups and MV-algebras: the category of unital commutative lattice-ordered groups is equivalent to the category of MV-monoidal algebras. Roughly speaking, the structures we call unital commutative lattice-ordered groups are unital Abelian lattice-ordered groups without the unary operation $x \mapsto -x$\mathrm{.}Theprimitiveoperationsare$+$,$\lor$,$\land$,$0$,$1$,$-1$. A prime example of these structures is $\mathbb{R}$, with the obvious interpretation of the operations. Analogously, MV-monoidal algebras are MV-algebras without the negation $x\mapsto \mathrm{\neg }x$. The primitive operations are $\oplus$, $\odot$, $\vee$, $\wedge$, $0$, $1$. A motivating example of MV-monoidal algebra is the negation-free reduct of the standard MV-algebra $[0, 1] \subseteq $\mathbb{R}$$. We obtain the original Mundici’s equivalence as a corollary of our main result.
