Resum

We will show the gravitational field quantization in a spacetime with a black hole, in the Loop Quantum Gravity aproach. We will construct the Hilbert space of quantum gravity states. In this formalism, it will apear an interesting connection between quantum gravity and Chern-Simons theory in the black hole horizon surface. In fact, the Hilbert space of the quantum geometry of this spacetime is a product of a Chern-Simons theory Hilbert space on the surface, and the usual Hilbert space, of LQG, of states in the bulk. The main achievement of this aproach is that offers the posibility of stimating the black hole entropy from a statistical viewpoint. We will show some calculations on this topic. New perspectives will be discussed.
