BTZ Black Hole Entropy in Loop Quantum Gravity and in Spin Foam Models

We present a comparison of the calculation of BTZ black hole entropy in loop quantum gravity and in spin foam models. We see that both give the same answer.Comment: 10 pages, 3 figures, Final version, improve

Black Hole Entropy in Loop Quantum Gravity and Number Theory

We show that counting different configurations that give rise to black hole entropy in loop quantum gravity is related to partitions in number theory.Comment: 6 page
