Hilbert格式中的Gröbner格式与完全交单项式理想

Gröbner scheme in the Hilbert scheme and complete intersection monomial ideals

Yuta Kambe

摘要:

设$k$是交换环,$S=k[x_0, \ldots, x_n]$是$k$上的多项式环.对于任何单名理想$J$,存在一个有限型的仿射$k$ -格式,称为Gröbner格式,它将$S$中所有初始理想为$J$的齐次约化Gröbner基参数化.在这里,我们函式地证明了Gröbner计划是一个局部封闭的Hilbert计划的子计划,如果$J$是一个饱和理想。在这个过程中,我们还表明,Gröbner计划由完全的交叉,如果$J$定义一个完整的交叉。

英文摘要:

Let $k$ be a commutative ring and $S=k[x_0, \ldots, x_n]$ be a polynomial ring over $k$ with a monomial order. For any monomial ideal $J$, there exists an affine $k$-scheme of finite type, called Gröbner scheme, which parameterizes all homogeneous reduced Gröbner bases in $S$ whose initial ideal is $J$. Here we functorially show that the Gröbner scheme is a locally closed subscheme of the Hilbert scheme if $J$ is a saturated ideal. In the process, we also show that the Gröbner scheme consists of complete intersections if $J$ defines a complete intersection.
