Hilbert点系的更基本的分支

More elementary components of the Hilbert scheme of points

Mark E. Huibregtse

摘要:

设$K$是特征$0$的代数闭域,$H^μ$表示仿射空间$A^n$的$μ$点的Hilbert概型. $H^μ$的基本分量$E$是不可约分量,使得每个$K$ -点$[I]$表示在一个点处支持的长度- $μ$封闭子方案规范$(K[x_1,\dots,x_n]/I)$ $\subseteq$ $A^n$.在前一篇文章中,我们发现了一些新的基本成分的例子;在这篇文章中,我们简化了方法,并扩展了前一篇文章的范围,以找到更多的例子。此外,我们提出了一个“可验证性测试”,表明存在大量类似的例子。

英文摘要:

Let $K$ be an algebraically closed field of characteristic $0$, and let $H^μ$ denote the Hilbert scheme of $μ$ points of the affine space $A^n$. An elementary component $E$ of $H^μ$ is an irreducible component such that every $K$-point $[I]$ $\in$ $E$ represents a length-$μ$ closed subscheme Spec$(K[x_1,\dots,x_n]/I)$ $\subseteq$ $A^n$ that is supported at one point. In a previous article we found some new examples of elementary components; in this article, we simplify the methods and extend the range of the previous paper to find several more examples. In addition, we present a "plausibility test" that suggests the existence of a vast number of similar examples.
