Some exact values of the Harborth constant and its plus-minus weighted analogue

Luz Elimar Marchan, Oscar Ordaz, Dennys Ramos +1

The Harborth constant of a finite abelian group is the smallest integer $ℓ$ such that each subset of $G$ of cardinality $ℓ$ has a subset of cardinality equal to the exponent…

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…
