From a finite set in a lattice, we can define a toric variety embedded in a projective space. In this paper, we give a combinatorial description of the dual defect of the toric variety using the structure of the finite set as a Cayley sum with suitable conditions. We also interpret the description geometrically.

复曲面品种双重缺陷的组合描述

从格中的有限集,我们可以定义嵌入射影空间的复曲面变体。在本文中,我们使用有限集的结构作为具有适当条件的凯莱和,对复曲面簇的对偶缺陷进行了组合描述。我们还以几何方式解释描述。
