自旋6-流形上的Kaehler结构

Kaehler structures on spin 6-manifolds

Stefan Schreieder, Luca Tasin

摘要:

我们发现,许多自旋6-流形的同伦型,但不是同胚型的Kaehler流形。此外,对于给定的贝蒂数,一般型光滑复射影自旋三重的变形类型和拓扑型只有1000种.最后,在一个固定的自旋6-流形上,陈数在所有可能的Kaehler结构上只取200个值。

英文摘要:

We show that many spin 6-manifolds have the homotopy type but not the homeomorphism type of a Kaehler manifold. Moreover, for given Betti numbers, there are only finitely many deformation types and hence topological types of smooth complex projectve spin threefolds of general type. Finally, on a fixed spin 6-manifold, the Chern numbers take on only finitely many values on all possible Kaehler structures.
