Z/pZ的大无零子集

Large zero-free subsets of Z/pZ

Jean-Marc Deshouillers, Gyan Prakash

摘要:

阿贝尔群$G$的有限子集$A$称为无零的,如果$G$的单位元不能写成与$A$不同的元素之和。本文研究了$Z/pZ$的零自由子集的结构,它的基数接近于最大可能。特别是,我们确定的基数的最大零自由子集的$Z/pZ$,当$p$是一个足够大的素数。

英文摘要:

A finite subset $A$ of an abelian group $G$ is said to be zero-free if the identity element of $G$ cannot be written as a sum of distinct elements from $A$. In this article we study the structure of zero-free subsets of $Z/pZ$ the cardinality of which is close to largest possible. In particular, we determine the cardinality of the largest zero-free subset of $Z/pZ$, when $p$ is a sufficiently large prime.
