双轴扰动下五维Schwarzschild度规的稳定性和衰减率

Stability and decay-rates for the five-dimensional Schwarzschild metric under biaxial perturbations

G. Holzegel

摘要:

本文证明了五维Schwarzschild度规在双轴真空扰动下的非线性渐近稳定性。这是这样的陈述,即五维史瓦西度规的初始数据的(SU(2)x U(1))-对称真空微扰的演化最终在适当的意义上收敛到史瓦西族的一个成员。它构成了第一个结果证明存在的非平稳真空黑洞所产生的渐近平坦的初始数据动态地接近一个固定的解决方案。事实上,我们展示了接近的定量率。证明依赖于向量场乘数估计,这是结合使用的自举参数建立多项式衰减率的扰动时空上的辐射。尽管在这里被应用在一个五维的上下文中,该技术是相当强大的,可以承认各种四维稳定性问题的应用。

英文摘要:

In this paper we prove the non-linear asymptotic stability of the five-dimensional Schwarzschild metric under biaxial vacuum perturbations. This is the statement that the evolution of (SU(2) x U(1))-symmetric vacuum perturbations of initial data for the five-dimensional Schwarzschild metric finally converges in a suitable sense to a member of the Schwarzschild family. It constitutes the first result proving the existence of non-stationary vacuum black holes arising from asymptotically flat initial data dynamically approaching a stationary solution. In fact, we show quantitative rates of approach. The proof relies on vectorfield multiplier estimates, which are used in conjunction with a bootstrap argument to establish polynomial decay rates for the radiation on the perturbed spacetime. Despite being applied here in a five-dimensional context, the techniques are quite robust and may admit applications to various four-dimensional stability problems.
