Schwarzschild黑洞的Harrison度量

Harrison metrics for the Schwarzschild black hole

Fang-Fang Yuan, Yong-Chang Huang

摘要:

基于隐共形对称性,一些作者提出了Schwarzschild黑洞的Harrison度规。我们给出了一个从SL(2,R)向量场的一般集合出发生成一族Harrison度量的过程。通过与Kerr黑洞的减几何类比,我们得到了Schwarzschild情形的一个新的Harrison度规。利用Killing方程在近视界极限下研究了它的共形生成元。

英文摘要:

Based on the hidden conformal symmetry, some authors have proposed a Harrison metric for the Schwarzschild black hole. We give a procedure which can generate a family of Harrison metrics starting from a general set of SL(2, R) vector fields. By analogy with the subtracted geometry of the Kerr black hole, we find a new Harrison metric for the Schwarzschild case. Its conformal generators are also investigated using the Killing equations in the near-horizon limit.
