On short zero-sum subsequences of zero-sum sequences

Yushuang Fan, Weidong Gao, Guoqing Wang +2

Let $G$ be a finite abelian group, and let $η (G)$ be the smallest integer $d$ such that every sequence over $G$ of length at least $d$ contains a zero-sum subsequence $T$ with leng…

Distinct Lengths Modular Zero-sum Subsequences: A Proof of Graham's Conjecture

Weidong Gao, Y. O. Hamidoune, Guoqing Wang

Let $n$ be a positive integer and let $S$ be a sequence of $n$ integers in the interval $[0, n - 1]$ . If there is an $r$ such that any nonempty subsequence with sum $\equiv 0$ $\pmod…
