On the anticanonical complex

Christoff Hische, Milena Wrobel

摘要:

反正则复形作为环面Fano多面体的自然推广而被引入,迄今为止已成功地用于研究具有环面作用的复杂性的变种。在本文中,我们扩大了应用领域的anticanonical复杂的品种与环面行动的复杂性更高,例如,一般安排品种。作为该方法的一个应用,我们对自同构群具有一维极大环面的三维标准Fano内禀二次曲面进行了分类。

英文摘要:

The anticanonical complex has been introduced as a natural generalization of the toric Fano polytope and so far has been succesfully used for the study of varieties with a torus action of complexity one. In the present article we enlarge the area of application of the anticanonical complex to varieties with a torus action of higher complexity, for example, general arrangement varieties. As an application of our techniques we classify the three-dimensional canonical Fano intrinsic quadrics with automorphism group having a maximal torus of dimension one.
