Multi-wise and constrained fully weighted Davenport constants and interactions with coding theory

Luz Elimar Marchan, Oscar Ordaz, Irene Santos +1

We consider two families of weighted zero-sum constants for finite abelian groups. For a finite abelian group $(G, +)$ , a set of weights $W \subset Z$ , and an integral…

Remarks on the plus-minus weighted Davenport constant

Luz Elimar Marchan, Oscar Ordaz, Wolfgang Schmid

For $(G, +)$ a finite abelian group the plus-minus weighted Davenport constant, denoted $D_{\pm} (G)$ , is the smallest $ℓ$ such that each sequence $g_{1} ... g_{ℓ}$ over…

A Weighted Generalization of Two Theorems of Gao

David J. Grynkiewicz, Luz Elimar Marchan, Oscar Ordaz

Let $G$ be a finite abelian group and let $A \subseteq Z$ be nonempty. Let $D_{A} (G)$ denote the minimal integer such that any sequence over $G$ of length $D_{A} (G)$ must conta…
