摘要翻译:
对于在极小G/P中与Schubert变体的Bruhat偏序集相关的toric变体X,我们用相关的多面体锥面来描述奇异轨迹。我们进一步证明了奇异轨迹在X中是余维数为3的纯的。

英文摘要:
For the toric variety X associated to the Bruhat poset of Schubert varieties in a minuscule G/P, we describe the singular locus in terms of the faces of the associated polyhedral cone. We further show that the singular locus is pure of codimension 3 in X.
