Kerr-Bolt时空与Kerr/CFT对应

Kerr-Bolt Spacetimes and Kerr/CFT Correspondence

A. M. Ghezelbash

摘要:

我们调查最近提出的Kerr/CFT对应的背景下,旋转时空与NUT扭曲。Kerr/CFT对应指出,极端四维(或更高)黑洞的近视界态可以用一定的手征共形场论来识别。相应的维拉索罗代数由一类在近视界几何上保持适当边界条件的单同态生成。我们试图理解的对偶手征CFT的背景下的奇点模拟。解释,我们使用克尔/CFT对应表明,如果我们最初不删除的奇异性从时空中,在双手征CFT中,我们可以检测到奇异性的存在,在大部分的时空。

英文摘要:

We investigate the recently proposed Kerr/CFT correspondence in the context of rotating spacetimes with a NUT twist. The Kerr/CFT correspondence states that the near-horizon states of an extremal four (or higher) dimensional black hole could be identified with a certain chiral conformal field theory. The corresponding Virasoro algebra is generated with a class of diffeomorphism which preserves an appropriate boundary condition on the near-horizon geometry. We try to understand the analog of singularities in the context of dual chiral CFT. Explicitly, we use Kerr/CFT correspondence to show that if we initially do not remove the singularities from the spacetimes, in the dual chiral CFT we can detect the presence of singularities in the bulk of spacetime.
