Grothendieck簇环上的幂结构与Hilbert点格式的生成列

Power structure over the Grothendieck ring of varieties and generating series of Hilbert schemes of points

Sabir M. Gusein-Zade, Ignacio Luengo, Alejandro Melle-Hernandez

摘要:

利用作者构造的复拟射影簇的Grothendieck(半)环上的幂结构,将光滑拟射影簇上零维子格式的Hilbert格式类的生成列表示为同维复仿射空间上的生成列的指数.这个关系的特殊化给出了生成一系列希尔伯特点格式的不变量的公式,如欧拉示性数和Hodge-Deligne多项式。

英文摘要:

The power structure over the Grothendieck (semi)ring of complex quasi-projective varieties constructed by the authors is used to express the generating series of classes of Hilbert schemes of zero-dimensional subschemes on a smooth quasi-projective variety as an exponent of that for the complex affine space of the same dimension. Specializations of this relation give formulae for generating series of such invariants of the Hilbert schemes of points as the Euler characteristic and the Hodge-Deligne polynomial.
