摘要：
We analyze the near horizon symmetry of the extremal Kerr black hole within the framework of Poincare & PRIME; gauge theory (PG) for two important limiting cases; Riemannian and teleparallel solution. We show that the algebra of canonical generators is realized by Virasoro algebra, with central charge which depends on the black hole horizon radius. The conformal entropy of the black hole is obtained via the Cardy formula.
