讲座内容：
Let $G$ be a finite abelian group and $\mathsf M(G,k)$ is the set of all zero-sum seqeunces over $G$ of length $k$. Zero-sum sequence is a classical object in additive combinatorics. In this talk, we show that the study of $\mathsf M(G,k)$ is closely related to some other interesting combinatorial problems: combinatorial reciprocity, cyclic sieving phenomenon, and Cayley tables of finite abelian groups.
