静态分解的唯一性

Uniqueness of static decompositions

Manuel Gutiérrez, Benjamín Olea

摘要:

我们分类静态流形,承认一个以上的静态分解时,曲率的条件是fullfilled。为此,我们采取一个标准的静态向量场,并分析其相关的一个参数家庭的基地上的投影。我们表明,基地本身是一个静态的流形和翘曲函数满足严格的限制,导致我们我们的分类结果。此外,我们还证明了类光截面曲率的某些条件保证了洛伦兹流形静态分解的唯一性。

英文摘要:

We classify static manifolds which admit more than one static decomposition whenever a condition on the curvature is fullfilled. For this, we take a standard static vector field and analyze its associated one parameter family of projections onto the base. We show that the base itself is a static manifold and the warping function satisfies severe restrictions, leading us to our classification results. Moreover, we show that certain condition on the lightlike sectional curvature ensures the uniqueness of static decomposition for Lorentzian manifolds.
