Let $H$ and $K$ be numerical monoids, and let $\mathcal{P}_{\operatorname{fin},1}(H)$ and $\mathcal{P}_{\operatorname{fin},1}(K)$ denote their reduced finitary power monoids, consi…

Let $S$ and $S'$ be numerical monoids. For a numerical monoid $T$, let $\mathcal P_{\mathrm{fin},0}(T)$ denote the power monoid of finite subsets of $T$ containing $0$. Isomorphism…
