Grassmannian中具有平凡典范丛的低维流形

Manifolds of low dimension with trivial canonical bundle in Grassmannians

Vladimiro Benedetti

摘要:

本文研究了平凡典范丛的四重性,其中平凡正则丛是普通复Grassmannian和经典复Grassmannian上齐次完全可约丛的截面的零轨迹。我们证明了其中唯一的HyperK hler四重是Beauville和Donagi的例子,以及Debarre和Voisin的例子。在这样做的时候,我们给出了这些品种的完整分类。我们也包括类似的分类表面和三重。

英文摘要:

We study fourfolds with trivial canonical bundle which are zero loci of sections of homogeneous, completely reducible bundles over ordinary and classical complex Grassmannians. We prove that the only HyperK{ä}hler fourfolds among them are the example of Beauville and Donagi, and the example of Debarre and Voisin. In doing so, we give a complete classification of those varieties. We include also the analogous classification for surfaces and threefolds.
