模空间上的Gauss-Bonnet-Chern定理

Gauss-Bonnet-Chern theorem on moduli space

Zhiqin Lu, Michael R. Douglas

摘要:

本文证明了极化Kahler流形的模空间上的Gauss-Bonnet-Chern定理。利用我们的结果,我们证明了CY模的Chern-Weil形式(关于Weil-Petersson度量)的合理性。作为物理学中的一个应用,根据Ashok-Douglas理论,计算Calabi-Yau三重空间上IIb型弦的通量紧化的个数与各种Chern-Weil形式的积分有关。我们证明了所有这些积分都是有限的(也是有理的)。

英文摘要:

In this paper, we proved the Gauss-Bonnet-Chern theorem on moduli space of polarized Kahler manifolds. Using our results, we proved the rationality of the Chern-Weil forms (with respect to the Weil-Petersson metric) on CY moduli. As an application in physics, by the Ashok-Douglas theory, counting the number of flux compactifications of the type IIb string on a Calabi-Yau threefold is related to the integrations of various Chern-Weil forms. We proved that all these integrals are finite (and also rational).
