Abstract

We show how the minimal free resolution of a set of $n$ points in general position in projective space of dimension $n-2$ explicitly determines structure constants for a ring of rank $n$. This generalises previously known constructions of Levi–Delone–Faddeev and Bhargava in the cases $n = 3, 4, 5$.

从最小自由决议计算有限秩环的结构常数

我们展示了在维数为 $n-2$ 的投影空间中，一组一般位置的 $n$ 点的最小自由分辨率如何明确地决定了秩为 $n$ 的环的结构常数。这推广了先前已知的列维-德隆-法迪夫和巴尔加瓦在 $n = 3、4、5$ 情况下的构造。
