On orders in quadratic number fields with unusual sets of distances

Andreas Reinhart

Let $O$ be an order in an algebraic number field and suppose that the set of distances $Δ (O)$ of $O$ is nonempty (equivalently, $O$ is not h…

On Monoids of plus-minus weighted Zero-Sum Sequences: The Isomorphism Problem and the Characterization Problem

Florin Fabsits, Alfred Geroldinger, Andreas Reinhart +1

Let $G$ be an additive abelian group. A sequence $S = g_{1} \cdot \dots \cdot g_{ℓ}$ of terms from $G$ is a plus-minus weighted zero-sum sequence if there are $\varepsilon_1,\ldots,\v…
