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 TuraevViro 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.
