AI总结:

本文证明了Kerr de Sitter时空扩张区域的非线性稳定性,通过ADM形式和Hintz-Vasy定理,展示了从空间样hypersurface数据得到的全局稳定性结果。

摘要:

我们证明了Kerr de Sitter时空的宇宙学区域的非线性稳定性。更确切地说,我们表明由在圆柱上给出的数据解的爱因斯坦真空方程,其正宇宙学常数的解,当该圆柱均匀接近Kerr de Sitter几何(可能在两端有不同的质量和角动量参数)时,是未来测地完备的,并且表现出渐近的de Sitter-like自由度。该证明使用了爱因斯坦方程的ADM形式在抛物线坐标系中的表述。结合Hintz-Vasy [Acta Math. 220 (2018)] 的一个已知定理,我们的结果从一个空间样hypersurface上的Cauchy数据得出Kerr de Sitter的全局稳定性结果,该hypersurface连接两个黑洞外部区域。

英文摘要:

We prove the nonlinear stability of the cosmological region of Kerr de Sitter spacetimes. More precisely, we show that solutions to the Einstein vacuum equations with positive cosmological constant arising from data on a cylinder that is uniformly close to the Kerr de Sitter geometry (with possibly different mass and angular momentum parameters at either end) are future geodesically complete and display asymptotically de Sitter-like degrees of freedom. The proof uses an ADM formulation of the Einstein equations in parabolic gauge. Together with a well-known theorem of Hintz-Vasy [Acta Math. 220 (2018)], our result yields a global stability result for Kerr de Sitter from Cauchy data on a spacelike hypersurface bridging two black hole exteriors.
