Hi PF
I am reading an old Rovelli paper http://arxiv.org/abs/gr-qc/9603063
Rovelli computes the entropy of a black hole.
He says two things.
a) A state is described with an equivalence class of s-knots.
b) the entropy of a black hole can be computed by counting the number of the intersection of the horizon and the s-knot (an equivalence class)
So when he writes :
Let i = 1...n label such intersections
What is this n? what is this i labelling?
