量子黑洞熵中出现的单环发散被证明可以通过有效引力作用中的 R(2) 项对引力常数和其他系数进行标准重整化来完全消除。证明的要点是，由于高阶曲率项，熵与爱因斯坦引力中的贝肯斯坦-霍金熵不同，其贡献取决于地平线表面的内部和外部几何形状。
One-loop divergences appearing in the entropy of a quantum black hole are proven to be completely eliminated by the standard renormalization of both the gravitational constant and other coefficients by the R(2)-terms in the effective gravitational action. The essential point of the proof is that due to the higher order curvature terms the entropy differs from the Bekenstein-Hawking one in the Einstein gravity by contributions depending on the internal and external geometry of the horizon surface.
