摘要：
At the horizon of a black hole, the action of (3 + 1)-dimensional loop quantum gravity acquires a boundary term that is formally identical to an action for three-dimensional gravity. I show how to use this correspondence to obtain the entropy of the (3 + 1)-dimensional black hole from well-understood conformal field theory computations of the entropy in (2 + 1)-dimensional de Sitter space.
