A Variant of Harborth Constant

A. Lemos, B. K. Moriya, A. O. Moura +1

Let $G$ be a finite additive abelian group. For given $k$ a positive integer, the $k$ -Harborth constant $g^{k} (G)$ is defined to be the smallest positive integer $t$ such that given…

On the Number of Weighted Zero-sum Subsequences

A. Lemos, B. K. Moriya, A. O. Moura +1

Let $G$ be a finite additive abelian group with exponent $d^{k} n, d, n > 1,$ and $k$ a positive integer. For $S$ a sequence over $G$ and $A=\{1,2,\ldots,d^kn-1\}\setminus\{d^kn/d^i:i\in…
