报告摘要: In 1961 P. Erd\H os ，A. Ginzburg and A. Ziv established the following EGZ theorem: Among any $2n-1$ integers one can choose $n$ of them such that their sum is a multiple of $n$. In this talk we introduce zero-sum problems of new types motivated by the EGZ theorem, and present some conjectures and results in this new direction.
