五维超引力中黑洞的隐藏对称性

Hidden symmetries of black holes in five-dimensional supergravity

David D. K. Chow

摘要:

我们考虑了五维STU超引力中的一般带电旋转黑洞,并证明了它的六维Kaluza-Klein升力具有带挠率的Killing-Yano 3-形式.这是已知的Killing张量在五维空间的基础,并且与挠率修正的狄拉克方程的可分性有关。在对规范超引力的推广中,我们给出了当两个规范场相等时的五维Killing-Yano 3-形式和3-电荷吴解中的Killing-Stackel张量.

英文摘要:

We consider a general charged, rotating black hole in five-dimensional STU supergravity, and show that its six-dimensional Kaluza-Klein lift admits a Killing-Yano 3-form with torsion. This underlies its known Killing tensors in five dimensions, and is related to the separability of torsion-modified Dirac equations. In the generalization to gauged supergravity, we present a five-dimensional Killing-Yano 3-form with torsion when two of the gauge fields are equal, and a Killing-Stackel tensor in the general 3-charge Wu solution.
