论文摘要
我们描述了正常孢子品种的非gorenstein基因座。在hibi环的情况下，根据基础部分排序的集合提供了组合描述。作为一种非态度，我们计算了第一个Segre品种的非Gorenstein基因座的尺寸。
We describe the non-Gorenstein loci of normal toric varieties. In the case of Hibi rings a combinatorial description is provided in terms of the underlying partially ordered set. As a non-toric application we compute the dimensions of the non-Gorenstein loci of the first secant variety of Segre varieties.
