In [5], Eklund showed that a general (ℤ/2ℤ)4 -invariant quartic K3 surface contains at least 320 conics. In this paper, we analyse the field of definition of those conics as well as their Monodromy group. As a result, we prove that the moduli space of (ℤ/2ℤ)4-invariant quartic K3 surface with a certain marked conic has 10 irreducible components.

关于位于海森堡不变量四次 K3 曲面上的二元和伽罗瓦群

在 [5] 中,Eklund 证明了一般 (ℤ/2ℤ)4- 不变的四次 K3 曲面包含至少 320 个圆锥曲线。在本文中,我们分析了这些圆锥曲线的定义域以及它们的 Monodromy 群。结果,我们证明了 (ℤ/2ℤ) 的模空间4-具有一定标记二次曲线的不变量四次 K3 曲面有 10 个不可约分量。
