On the Index of Sequences over Cyclic Groups

Weidong Gao, Yuanlin Li, Jiangtao Peng +2

Let $G$ be a finite cyclic group of order $n \geq 2$ . Every sequence $S$ over $G$ can be written in the form $S = (n_{1} g) \cdot ... \cdot (n_{l} g)$ where $g \in G$ and $n_1,..., n_l \in [1…

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…
