Title: Quantum topological invariants and black hole entropy
Abstract: A type of topological invariants of three manifolds were introduced by Turaev and Viro. We will define an invariant of graphs embedded in a three dimensional manifold in a Turaev-Viro spirit.The relation of these invariants to mathematical physics isa really nice one. We will show how entropy of a three dimensionalblack hole known as BTZ can be described using our formulation.
