HYPERBOLIC STRUCTURE ARISING FROM A KNOT INVARIANT
International Journal of Modern Physics A
We study the knot invariant based on the quantum dilogarithm function. This invariant can be regarded as a non-compact analogue of Kashaev's invariant, or the colored Jones invariant, and is defined by an integral form. The 3-dimensional picture of our invariant originates from the pentagon identity of the quantum dilogarithm function, and we show that the hyperbolicity consistency conditions in gluing polyhedra arise naturally in the classical limit as the saddle point equation of our invariant.doi:10.1142/s0217751x0100444x fatcat:zblvajqivngcbjbdoat7hldjka
