具有常全纯sectional curvature的多闭流形

Pluriclosed manifolds with constant holomorphic sectional curvature

Peipei Rao, Fangyang Zheng

摘要:

复几何中一个长期存在的猜想说,一个具有常全纯截面曲率的紧致厄米流形当常数不为零时一定是凯勒流形,当常数为零时一定是陈平坦流形。这个猜想在复维数$2$中被Balas-Gauduchon在1985年的工作(当常数为零或负)和Apostolov-Davidov-Muskarov在1996年的工作(当常数为正)所知。对于更高的维度,这个猜想在很大程度上仍然是未知的。在这篇文章中,我们将自己限制在多重闭流形,并确认了Strominger Kähler-like流形的特殊情况下的猜想,即,对于Hermitian流形,其Strominger连接(也称为Bismut连接)服从所有的Kähler对称性。

英文摘要:

A long-standing conjecture in complex geometry says that a compact Hermitian manifold with constant holomorphic sectional curvature must be Kähler when the constant is non-zero and must be Chern flat when the constant is zero. The conjecture is known in complex dimension $2$ by the work of Balas-Gauduchon in 1985 (when the constant is zero or negative) and by Apostolov-Davidov-Muskarov in 1996 (when the constant is positive). For higher dimensions, the conjecture is still largely unknown. In this article, we restrict ourselves to pluriclosed manifolds, and confirm the conjecture for the special case of Strominger Kähler-like manifolds, namely, for Hermitian manifolds whose Strominger connection (also known as Bismut connection) obeys all the Kähler symmetries.
