具有S5-action的K3族的周期图
Period map of a certain K3 family with an S5-action
摘要:
本文研究了一类单参数四次K3曲面族在S5作用下的周期映射。通过模嵌入,我们构造了周期域上的自守形式作为亏格2的θ常数的拉回。利用这些自守形式,我们给出了反周期映射的一个显式表示。
英文摘要:
In this paper, we study the period map of a certain one-parameter family of quartic K3 surfaces with an S5-action. We construct automorphic forms on the period domain as the pull-backs of theta constants of genus 2 by a modular embedding. Using these automorphic forms, we give an explicit presentation of the inverse period map.
