Title: Zero-sum subsequences of distinct lengths

Abstract:

Let $G$ be an additive finite abelian group, and let $\mbox{disc}(G)$ denote the smallest positive integer $t$ such that every sequence $S$ over $G$ of length $|S|\geq t$ has two nonempty zero-sum subsequences of distinct lengths. We present some recent results and some open problems on $\mbox{disc}(G)$.
