任意理想的有效零点空间

Effective Nullstellensatz for Arbitrary Ideals

János Kollár

摘要:

设$f_i$是$n$变量中没有公共零点的多项式。希尔伯特的零点定理说存在多项式$g_i$使得$\sum g_if_i=1$。该结果的有效版本根据$f_j$的度来约束$g_i$的度。本文的目的是推广到的情况下,当$f_i$被替换为任意理想。应用到Bézout定理,以Eschojasiewicz-型不等式和变形理论也进行了讨论。

英文摘要:

Let $f_i$ be polynomials in $n$ variables without a common zero. Hilbert's Nullstellensatz says that there are polynomials $g_i$ such that $\sum g_if_i=1$. The effective versions of this result bound the degrees of the $g_i$ in terms of the degrees of the $f_j$. The aim of this paper is to generalize this to the case when the $f_i$ are replaced by arbitrary ideals. Applications to the Bézout theorem, to Łojasiewicz--type inequialities and to deformation theory are also discussed.
