修正对角闭链的周群消没结果

Vanishing results in Chow groups for the modified diagonal cycles

Congling Qiu, Wei Zhang

AI总结:

本文给出了曲线上三重积周群中修正对角闭链消没的一个充分条件,并构造了无穷多个满足该条件的非超椭圆曲线实例。

摘要:

我们证明了一个充分条件,用于判定在复数域上曲线的三重积的周群(以$\mathbb{Q}$为系数)中修正对角闭链的消没性。我们展示了无穷多个非超椭圆曲线,包括Fricke--Macbeath曲线、Bring曲线,以及由某些Hurwitz空间参数化的两个一维族,均满足我们的条件。

英文摘要:

We prove a sufficient condition for the vanishing of the modified diagonal cycle in the Chow group (with $\mathbb{Q}$-coefficients) of the triple product of a curve over $\mathbb{C}$. We exhibit infinitely many non-hyperelliptic curves, including the Fricke--Macbeath curve, the Bring curve, and two 1-dimensional families parameterized by certain Hurwitz spaces, for which our condition is satisfied.
