极小补数的渐近性质
Asymptotic behaviour of minimal complements
摘要:
极小补的概念是由Nathanson在2011年引入的,作为网的度量概念的自然群论类似物。给定群$G$中的两个非空子集$W,W'$,如果$W\cdot W'=G$,则集合$W'$称为$W$的补集,如果没有$W'$的真子集是$W$的补集,则它是最小的。逆问题是问哪些集合可以或不可以作为最小补集出现。我们展示了一些新的反问题的结果,并探讨如何自然地产生的问题,这些集的渐近行为的反问题的研究,其中一些提供部分答案。
英文摘要:
The notion of minimal complements was introduced by Nathanson in 2011 as a natural group-theoretic analogue of the metric concept of nets. Given two non-empty subsets $W,W'$ in a group $G$, the set $W'$ is said to be a complement to $W$ if $W\cdot W'=G$ and it is minimal if no proper subset of $W'$ is a complement to $W$. The inverse problem asks which sets may or not occur as minimal complements. We show some new results on the inverse problem and investigate how the study of the inverse problem naturally gives rise to questions about the asymptotic behaviour of these sets, providing partial answers to some of them.
