瞬时完全的陈-里奇流和凯勒-爱因斯坦度规

Instantaneously complete Chern-Ricci flow and Kähler-Einstein metrics

Shaochuang Huang, Man-Chun Lee, Luen-Fai Tam

摘要:

在这篇工作中,我们得到了复流形上的里奇流和相应的势流在可能不完全初始数据下的存在性结果。我们讨论解的行为为$t\rightarrow 0$。这些结果在一定意义上可以看作是Giesen和Topping关于双曲型曲面里奇流的存在性结果在高维上的推广。另一方面,我们还讨论了解的长时间性态,得到了完备非紧Hermitian流形上Kähler-Einstein度量存在的一些充分条件,推广了Lott-Zhang和Tosatti-Weinkove的工作到曲率可能无界的完备非紧Hermitian流形上.

英文摘要:

In this work, we obtain some existence results of Chern-Ricci Flows and the corresponding Potential Flows on complex manifolds with possibly incomplete initial data. We discuss the behaviour of the solution as $t\rightarrow 0$. These results can be viewed as generalization of an existence result by Giesen and Topping for surfaces of hyperbolic type of Ricci flow to higher dimensions in certain sense. On the other hand, we also discuss the long time behaviour of the solution and obtain some sufficient conditions for the existence of Kähler-Einstein metric on complete noncompact Hermitian manifolds, which generalizes the work of Lott-Zhang and Tosatti-Weinkove to complete noncompact Hermitian manifolds with possibly unbounded curvature.
