摘要:

最近的研究表明,在非相对论性和近视界的情况下,在边界上施加Petrov I型条件,可以将Einstein方程简化为纳维-斯托克斯方程。在本文中,我们将这个框架扩展到具有宇宙学常数的时空。通过显式构造,我们证明了纳维-斯托克斯方程可以从黑膜背景和空间弯曲时空导出。我们还推测,在边界上施加彼得罗夫I型条件应与在近视界极限使用度规的流体动力学展开的常规方法等价。

英文摘要:

Recently it has been shown that imposing Petrov type I condition on the boundary may reduce the Einstein's equation to the Navier-Stokes equation in the non-relativistic and near-horizon limit. In this paper we extend this framework to a spacetime with a cosmological constant. By explicit construction we show that the Navier-Stokes equation can be derived from both black brane background and spatially curved spacetime. We also conjecture that imposing Petrov type I condition on the boundary should be equivalent to the conventional method using the hydrodynamical expansion of the metric in the near horizon limit.
