Abstract

Let L\mathcal L^* be a family of finite subsets of N0\mathbb N_0 having the following properties. (a). {0},{1}L\{0\}, \{1\} \in \mathcal L^* and all other sets of L\mathcal L^* lie in N2\mathbb N_{\ge 2}. (b). If L1,L2LL_1, L_2 \in \mathcal L^*, then the sumset L1+L2LL_1 + L_2 \in \mathcal L^*. We show that there is a Dedekind domain DD whose system of sets of lengths equals L\mathcal L^*.
