论文摘要
在本文中,我们在有限环上研究了矢量空间中的点产品集和$ k $ -simplices。我们表明,如果$ e $足够大,那么$ e $的点产品集涵盖了整个戒指。在较高维度的情况下,如果$ e $足够大,那么由$ e $确定的一组简单和一组点产品简单,直到富集,具有正密度。
In this paper, we study dot-product sets and $k$-simplices in vector spaces over finite rings. We show that if $E$ is sufficiently large then the dot-product set of $E$ covers the whole ring. In higher dimensional cases, if $E$ is sufficiently large then the set of simplices and the set of dot-product simplices determined by $E$, up to congurence, have positive densities.
