| Outline of Final Research Achievements |
Volume conjecture for knots states that, for a knot in 3-sphere, the volume of its complement appears in the limit of its Jones polynomial. This is very important conjecture because the geometric back ground of quantum invariants such as Jones polynomials is not clear yet. To prove this conjecture, we have to study the geometric property of the potential function which appears in the integral expression of the Jones polynomial of the knot. In fact, it is already know that the stationary phase equations and a critical value of the potential function give the structure equations and the complex volume of the knot.
In this research, we prove that the Hessian of the potential function gives the cusp shape, a geometric invariant of knots. Furthermore, we give a formula for the generalized cusp shape in terms of the potential function.
