微局域爱因斯坦度规的因果结构

The causal structure of microlocalized Einstein metrics

S. Klainerman, I. Rodnianski

摘要:

这是第二次在一系列的三篇论文中,我们开始研究非常粗糙的解决方案的初值问题的爱因斯坦真空方程表示相对于波坐标。我们所说的非常粗糙是指不能用能量估计和Sobolev不等式的经典技巧构造的解。本文对微局域粗糙爱因斯坦度规的Eikinal方程进行了几何分析。这是在我们的第一篇论文中所需要的衰变估计的推导中的关键一步。

英文摘要:

This is the second in a series of three papers in which we initiate the study of very rough solutions to the initial value problem for the Einstein vacuum equations expressed relative to wave coordinates. By very rough we mean solutions which cannot be constructed by the classical techniques of energy estimates and Sobolev inequalities. In this paper we develop the geometric analysis of the Eikinal equation for microlocalized rough Einstein metrics. This is a crucial step in the derivation of the decay estimates needed in our first paper.
