关于胖点的等变Hilbert格式类的生成列

On generating series of classes of equivariant Hilbert schemes of fat points

S. M. Gusein-Zade, I. Luengo, A. Melle Hernandez

摘要:

在以前的文章中,作者给出了在复拟射影簇的Grothendieck环上,在光滑簇和轨道上的零维Hilbert子格式的类级数的生成公式,并给出了相应环上的幂结构.在这里,我们给出了类似的这些公式的等变(相对于一个行动的有限群的光滑簇)希尔伯特计划的零维子计划和计算一些本地生成系列的行动的循环群在光滑表面上。

英文摘要:

In previous papers the authors gave formulae for generating series of classes (in the Grothendieck ring of complex quasi-projective varieties) of Hilbert schemes of zero-dimensional subschemes on smooth varieties and on orbifolds in terms of certain local data and the, so called, power structure over the corresponding ring. Here we give an analogue of these formulae for equivariant (with respect to an action of a finite group on a smooth variety) Hilbert schemes of zero-dimensional subschemes and compute some local generating series for an action of the cyclic group on a smooth surface.
