双多项式希尔伯特函数

Bipolynomial Hilbert functions

E. Carlini, M. V. Catalisano, A. V. Geramita

摘要:

设X是一个闭子概形,HF(X,-)和hp(X,-)分别表示X的Hilbert函数和Hilbert多项式.我们说X有双多项式Hilbert函数,如果对每个非负整数d,HF(X,d)=min{hp(P^n,d),hp(X,d)}.证明了如果X由平面和一般直线组成,则X有双多项式Hilbert函数。我们还猜想不相交线性空间的一般构形具有双多项式Hilbert函数。

英文摘要:

Let X be a closed subscheme and let HF(X,-) and hp(X,-) denote, respectively, the Hilbert function and the Hilbert polynomial of X. We say that X has bipolynomial Hilbert function if HF(X,d)=min{hp(P^n,d),hp(X,d)} for every non-negative integer d. We show that if X consists of a plane and generic lines, then X has bipolynomial Hilbert function. We also conjecture that generic configurations of non-intersecting linear spaces have bipolynomial Hilbert function.
