一类具有交换型模的特殊三次四重多项式

A family of special cubic fourfolds with motive of abelian type

Hanine Awada, Michele Bolognesi, Claudio Pedrini

摘要:

本文证明了在特殊三次四重数的每个Hassett因子内存在一维三次四重数族,其Chow动机为阿贝尔型,且维数有限.这也意味着相关Hyperkähler变种的动机的abelianity和有限维性,例如Fano线变种和LLSvS 8倍。

英文摘要:

In this short note, we show that there exist one dimensional families of cubic fourfolds with Chow motive of abelian type and finite dimensional inside every Hassett divisor of special cubic fourfolds. This also implies abelianity and finite dimensionality of the motive of related Hyperkähler varieties, such as the Fano variety of lines and the LLSvS 8fold.
