完备零锥上弱衰变下滞后时间的局部存在性

Local existence in retarded time under a weak decay on complete null cones

Junbin Li, Xi-Ping Zhu

摘要:

在前一篇文章\cite{L-Z}中,对于一个在完全零锥上衰减的特征问题,初始数据不一定很小,就像Christodoulou和Klainerman关于Minkowski时空稳定性的工作\cite{Ch-K}中的那样,我们证明了延迟时间的局部存在性,即真空Einstein方程的解存在于一致的未来邻域中,而推迟时间的整体存在性则是弱宇宙监督猜想。在本文中,我们证明了在延迟时间的局部存在性仍然成立时,数据被假定为衰减较慢,如在Bieri的工作\cite{Bie}的推广闵可夫斯基时空的稳定性。这样的衰减保证了在初始零锥上的霍金质量极限的存在,当接近无穷大时,以最佳的方式。

英文摘要:

In the previous paper \cite{L-Z}, for a characteristic problem with not necessarily small initial data given on a complete null cone decaying like that in the work \cite{Ch-K} of the stability of Minkowski spacetime by Christodoulou and Klainerman, we proved the local existence in retarded time, which means the solution to the vacuum Einstein equations exists in a uniform future neighborhood, while the global existence in retarded time is the weak cosmic censorship conjecture. In this paper, we prove that the local existence in retarded time still holds when the data is assumed to decay slower, like that in Bieri's work \cite{Bie} on the extension to the stability of Minkowski spacetime. Such decay guarantees the existence of the limit of the Hawking mass on the initial null cone, when approaching to infinity, in an optimal way.
