Proofs and disproofs of some conjectures on zero-sum problems of new types

Yang Li, San Ling, Zhonghua Sun +1

For integers $r \geq 1$ and $n \geq 2$ , let $s_{r} (n)$ be the least $N$ such that every sequence of $N$ vectors in $Z^{r}$ , each nonzero modulo $n$ , contains $n$ terms whose sum is zero mod…
