关于零圈和有理点的纤维化方法

On the fibration method for zero-cycles and rational points

Yonatan Harpaz, Olivier Wittenberg

摘要:

关于数域上任意光滑投射簇上存在零圈的猜想是由Colliot-Thélène,Santiago,Kato和Saito在20世纪80年代提出的。我们证明,这些结构是兼容的纤维化,纤维化成理性连接品种的曲线。特别地,它们对于具有连通几何稳定子的线性群的齐性空间的族的全空间成立。我们证明了类似的结果为有理点,条件上的猜想局部分裂值的多项式,最近的工作Matthiesen建立在线性多项式的情况下的理性。

英文摘要:

Conjectures on the existence of zero-cycles on arbitrary smooth projective varieties over number fields were proposed by Colliot-Thélène, Sansuc, Kato and Saito in the 1980's. We prove that these conjectures are compatible with fibrations, for fibrations into rationally connected varieties over a curve. In particular, they hold for the total space of families of homogeneous spaces of linear groups with connected geometric stabilisers. We prove the analogous result for rational points, conditionally on a conjecture on locally split values of polynomials which a recent work of Matthiesen establishes in the case of linear polynomials over the rationals.
