Anti-de Sitter空间的高阶扰动与真空Einstein方程的时间周期解

Higher order perturbations of Anti-de Sitter space and time-periodic solutions of vacuum Einstein equations

Andrzej Rostworowski

摘要:

受Anti-de Sitter(AdS)时空稳定性问题的启发,我们讨论了真空Einstein方程最大对称解的非线性引力扰动,特别是AdS情形.我们提出的证据表明,类似于自引力标量场在球对称,负的宇宙学常数允许存在全局正则,渐近AdS,时间周期解的真空爱因斯坦方程的频率分叉从线性本征频率的AdS。有趣的是,我们的初步结果表明,从一个给定的本征频率分叉的时间周期解的一个参数的家庭的数量等于这个本征频率的多重性。

英文摘要:

Motivated by the problem of stability of Anti-de Sitter (AdS) spacetime, we discuss nonlinear gravitational perturbations of maximally symmetric solutions of vacuum Einstein equations in general and the case of AdS in particular. We present the evidence that, similarly to the self-gravitating scalar field at spherical symmetry, the negative cosmological constant allows for the existence of globally regular, asymptotically AdS, time-periodic solutions of vacuum Einstein equations whose frequencies bifurcate from linear eigenfrequencies of AdS. Interestingly, our preliminary results indicate that the number of one parameter families of time-periodic solutions bifurcating from a given eigenfrequency equals the multiplicity of this eigenfrequency.
