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 , a set of weights , and an integral…

On the Olson and the Strong Davenport constants
Oscar Ordaz, Andreas Philipp, Irene Santos +1
A subset of a finite abelian group, written additively, is called zero-sumfree if the sum of the elements of each non-empty subset of is non-zero. We investigate the maxima…
