利用projective varieties的Hadamard积求$\mathbb{P}^3$中的Gorenstein点

Gorenstein points in $\mathbb{P}^3$ via Hadamard product of projective varieties

Cristiano Bocci, Chiara Capresi, Daniele Carrucoli

摘要:

我们展示了如何构建一个简笔画的线条在$\mathbb{P}^3$使用阿达玛产品的投影品种。然后,应用Migliore和Nagel的结果,我们使用这样的简笔画来构建具有给定$h-$向量${\mathbf h}$的Gorenstein点集。由于阿达玛产品是一个坐标明智的产品,我们显示,在结束时,如何坐标的点,在Gorenstein集,可以直接确定。

英文摘要:

We show how to construct a stick figure of lines in $\mathbb{P}^3$ using the Hadamard product of projective varieties. Then, applying the results of Migliore and Nagel, we use such stick figure to build a Gorenstein set of points with given $h-$vector ${\mathbf h}$. Since the Hadamard product is a coordinate-wise product, we show, at the end, how the coordinates of the points, in the Gorenstein set, can be directly determined.
