The exponential blueshift associated with the event horizon of a black hole makes conformal symmetry play a fundamental role in accounting for its thermal properties. Using a derivation based on two-point functions, we show that the full spectrum of thermal radiation of scalar particles by Kerr black holes can be explicitly derived on the basis of a conformal symmetry arising in the wave equation near the horizon. The simplicity of our approach emphasizes the depth of the connection between conformal symmetry and black hole radiance.
黑洞事件视界的指数蓝移使得共形对称性在解释其热性质方面起着基本作用。利用基于两点函数的推导，我们表明，克尔黑洞的标量粒子热辐射的全谱可以基于在视界附近的波动方程中出现的共形对称性明确推导出来。我们方法的简单性强调了共形对称性和黑洞辐射之间的紧密联系。
