Asymptotic symmetries of black holesComments: 13 pages, 8 figures, references added
We study asymptotic symmetries of the black hole geometry for a class of spaces in which the absolute zero temperature and the relative zero temperature are the same. In particular, we compute the asymptotic asymptotic symmetry for the black hole for the spacetime of a black hole horizon. We also show that the asymptotic asymptotic symmetry for the black hole is unique in the black hole horizon. We point out that the asymptotic asymptotic symmetry appears for the black holes at the horizon.
