标题： Horizon/Matter Systems near the Extreme State

摘要： 研究表明，在表面引力为零但局部温度非零的极端极限情况下，一般静态黑洞的极限度规由视界上的诱导度规和一个二维坐标的函数决定，源的应力-能量张量从视界获取其值。 该极限过程被扩展到旋转黑洞。 如果极端极限是由于黑洞视界和宇宙学视界合并，则在该极限下两个视界总是处于热平衡。 这已在一般静态或轴对称旋转时空的情况下得到证明。 显示英文摘要

摘要： It is shown that in the extreme limit with a zero surface gravity but nonzero local temperature the limiting metric of a generic static black hole is determined by a metric induced on a horizon and one function of two coordinates, stress-energy tensor of a source picking up its values from a horizon. The limiting procedure is extended to rotating black holes. If the extreme limit is due to merging a black hole horizon and cosmological one both horizons are always in thermal equilibrium in this limit. This is proved for a generic case of static or axially-symmetrical rotating spacetimes.
