三维流形上的数量曲率、度量退化和静态真空Einstein方程,I

Scalar curvature, metric degenerations and the static vacuum Einstein equations on 3-manifolds, I

Michael T. Anderson

摘要:

本文研究了任意闭三维流形M上的Yamabe度量及其模空间。主要研究了模空间的边界表现,即M上单位体积Yamabe度量退化序列的表现.证明了这种简并在一定意义下是非平凡的,可以用静态真空爱因斯坦方程的解来描述。给出了退化序列非平凡性的自然条件,并探讨了Einstein-Hilbert泛函与Palais-Smale序列的关系。一些新的例子,平凡的和非平凡的,退化序列的构造。证明了唯一的不含视界的完全静态真空解是平坦度规,推广了Lichnerowicz的一个经典结果。

英文摘要:

We study Yamabe metrics, and the moduli space of Yamabe metrics, on an arbitrary closed 3-manifold M. The main focus is on the boundary behavior of the moduli space, i.e. the behavior of degenerating sequences of unit volume Yamabe metrics on M. It is proved that such degenerations, when non-trivial in a certain sense, are described by solutions of the static vacuum Einstein equations. Natural conditions are given for the non-triviality of degenerating sequences and relations with Palais-Smale sequences for the Einstein-Hilbert functional are explored. A number of new examples, both trivial and non-trivial,of degenerating sequences are constructed. It is also proved that the only complete static vacuum solution without horizon is the flat metric, generalizing a classical result of Lichnerowicz.
