Extremal Kerr-AdS black hole with torsion: near-horizon geometry
САЖЕТАК:
Despite the face that extremal black holes in general relativity have a well defined concept of near-horizon geometry, it is not always the case in the presence of torsion. Covariant geometric conditions of existence of the near-horizon limit, which defines this geometry, are derived for the case of non-zero torsion. Finally, a model of Kerr-AdS black hole with torsion which has a well defined near-horizon geometry in the extremal case, is presented.
