非紧空间类Cauchy超曲面的规定中曲率流

Prescribed mean curvature flow of non-compact space-like Cauchy hypersurfaces

Giuseppe Gentile, Boris Vertman

摘要:

本文考虑广义Robertson-Walker时空中有界几何的非紧空间类Cauchy超曲面的规定中曲率流。我们证明了流保持类空条件,并存在无限时间。我们还证明了收敛的设置与边界的流形。我们的讨论推广了Ecker,Huisken,Gerhardt等人以前的工作,在一个关键方面:我们考虑了在有界几何假设下的任何非紧Cauchy超曲面。此外,我们专门考虑全球双曲洛伦兹时空配备了一个特定的类的翘曲产品度量上述作品。

英文摘要:

In this paper we consider the prescribed mean curvature flow of a non-compact space-like Cauchy hypersurface of bounded geometry in a generalized Robertson-Walker space-time. We prove that the flow preserves the space-likeness condition and exists for infinite time. We also prove convergence in the setting of manifolds with boundary. Our discussion generalizes previous work by Ecker, Huisken, Gerhardt and others with respect to a crucial aspects: we consider any non-compact Cauchy hypersurface under the assumption of bounded geometry. Moreover, we specialize the aforementioned works by considering globally hyperbolic Lorentzian space-times equipped with a specific class of warped product metrics.
