FEYNMAN''S PATH-INTEGRAL METHOD AND HAWKING EVAPORATION
费曼路径积分和霍金蒸发

Though there are various methods in deriving the Hawking evaporation formula, but all of them depend on explicit forms of the space-time metrics. Not long ago, we have put forward a conjecture. "Independent of the explicit forms of space-time metrics, every static or stationary space-time with furture horizon must have Hawking evaporation." Now in this paper, we give a full proof of this conjecture.
