关于泛超椭圆曲线的截面

On the sections of universal hyperelliptic curves

Tatsunari Watanabe

摘要:

本文给出了当$g\geq 3$和$\ell$ -进分圆特征标$G_k\to \Z^\times$的象为无穷大时,确定泛尖超椭圆曲线截面的代数证明.此外,我们将研究与泛超椭圆曲线相关的非交换现象。例如,我们将表明,部分猜想成立的普遍超椭圆曲线没有标记点和幂等类似的猜想成立的点的情况下。这项工作是一个扩展海恩的原始工作的超椭圆的情况下。

英文摘要:

In this paper, we will give an algebraic proof for determining the sections for the universal pointed hyperelliptic curves, when $g\geq 3$ and the image of the $\ell$-adic cyclotomic character $G_k\to \Z^\times$ is infinite. Furthermore, we will study the nonabelian phenomena associated to the universal hyperelliptic curves. For example, we will show that the section conjecture holds for the universal hyperelliptic curve without marked points and the unipotent analogue of the conjecture holds for the pointed case. This work is an extension of Hain's original work to the hyperelliptic case.
