Deformations of ordinary varieties of K3 type can be described in terms of displays by recent work of Langer-Zink. We extend this to the general (non-ordinary) case using displays with $G$-structure for a reductive group $G$. As a basis we suggest a modified definition of the tensor category of displays and variants which is similar to the Frobenius gauges of Fontaine-Jannsen.

更高的帧数和 G 显示器

Langer-Zink 最近的工作可以用显示来描述 K3 型普通品种的变形。我们将其扩展到一般（非普通）情况，使用具有 $G$ 结构的显示用于还原组 $G$。作为基础，我们建议对显示和变体的张量类别进行修改定义，该定义类似于 Fontaine-Jannsen 的 Frobenius 规范。
