For a general cubic fourfold X⊂P5 with Fano variety F, we compute the Hodge numbers of the locus S⊂F of lines of second type and the class of the locus V⊂F of triple lines, using the description of the latter in terms of flag varieties. We also give an upper bound of 6 for the degree of irrationality of the Fano scheme of lines of any smooth cubic hypersurface.

对于具有Fano变种F的一般三次四重X⊂P5，我们计算了第二类直线的轨迹S 8834F的Hodge数和三重直线的轨迹V 8834f的类，使用后者的旗变种描述。我们还给出了任意光滑三次超曲面的线的Fano格式的不合理度的上界6。

Perverse schobers and Orlov equivalences. 反常的学派和奥尔洛夫等同。

A perverse schober is a categorification of a perverse sheaf proposed by Kapranov-Schechtman. In this paper, we construct examples of perverse schobers on the Riemann sphere, which categorify the intersection complexes of natural local systems arising from the mirror symmetry for Calabi-Yau hypersurfaces. The Orlov equivalence plays a key role for the construction.

反常舍伯是Kapranov-Schechtman提出的对反常束的一种分类。在本文中，我们构造了Riemann球上的反常子的例子，它们分类了由Calabi-Yau超曲面的镜像对称产生的自然局部系统的交复合体。Orlov等价在构建过程中起着关键作用。
