Inverse results for weighted Harborth constants

Luz Elimar Marchan, Oscar Ordaz, Dennys Ramos +1

For a finite abelian group $(G, +)$ the Harborth constant is defined as the smallest integer $ℓ$ such that each squarefree sequence over $G$ of length $ℓ$ has a subsequence of…

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…
