球对称黑洞时空视界上应力能张量的Hadamard重整化
Hadamard Renormalisation of the Stress Energy Tensor on the Horizons of a Spherically Symmetric Black Hole Space-Time
摘要：
本文考虑在一般球对称黑洞时空中传播的Hartle-Hawking态量子场。我们利用均匀近似的径向方程来计算应力张量的分量，重整化使用阿达玛形式的格林函数，在这个时空的视野。然后，我们专门这些结果的情况下的“不冷不热”Reissner-Nordstrom-deSitter黑洞和导出的应力张量的规律性的Hartle-Hawking状态的一些条件。
英文摘要：
We consider a quantum field which is in a Hartle-Hawking state propagating in a general spherically symmetric black hole space-time. We make use of uniform approximations to the radial equation to calculate the components of the stress tensor, renormalized using the Hadamard form of the Green's function, on the horizons of this space-time. We then specialize these results to the case of the `lukewarm' Reissner-Nordstrom-de Sitter black hole and derive some conditions on the stress tensor for the regularity of the Hartle-Hawking state.
