Nef和大类的Kobayashi-Hitchin对应

The Kobayashi-Hitchin correspondence for nef and big classes

The University of Osaka(大阪大学)

Satoshi Jinnouchi

AI总结:

通过引入适应闭正(1,1)-流和适应Hermitian-Yang-Mills度量的概念,建立了nef和大上同调类的Kobayashi-Hitchin对应,并应用于Bogomolov-Gieseker不等式和Miyaoka-Yau不等式的等式情形。

摘要:

在本文中,我们通过引入适应闭正(1,1)-流和适应Hermitian-Yang-Mills度量的概念,建立了nef和大上同调类的Kobayashi-Hitchin对应。作为应用,我们研究了关于允许双亚纯Zariski分解的大类的半稳定自反层的Bogomolov-Gieseker不等式以及具有大反典范除子的射影簇的Miyaoka-Yau不等式的等式情形。

英文摘要:

In this paper, we establish the Kobayashi-Hitchin correspondence for nef and big cohomology classes by introducing the notions of adapted closed positive $(1,1)$-currents and adapted Hermitian-Yang-Mills metrics. As applications, we investigate the equality cases of both the Bogomolov-Gieseker inequality for semistable reflexive sheaves with respect to big classes admitting a bimeromorphic Zariski decomposition and the Miyaoka-Yau inequality for projective varieties with big anti-canonical divisor.
