Abstract

We exhibit examples of pairs $(X,D)$ where $X$ is a smooth projective variety and $D$ is an anticanonical reduced simple normal crossing divisor such that the deformations of $(X,D)$ are obstructed. These examples are constructed via toric geometry.

$\log$ Calabi-Yau 对的变形可能受阻

我们举例说明了一对 $(X,D)$，其中 $X$ 是光滑的投影变种，$D$ 是反谐函数的还原简单正交除数，从而使 $(X,D)$ 的变形受阻。这些例子是通过环几何构造的。
