introduction

  • The hyperbolic volume of a knot complement can be calculated using the Jones polynimials of the ca
  • $SU(2)$ connections on $S^3-K$ should be sensitive to the flat $SL_2(C)$ connection defining its hyperbolic structure
  • hyperbolic volume is closely related to the Cherm-Simons invariant
  • volume conjecture has its complexified version


Kashaev invariant

  • invariant of a link using the R-matrix
  • calculate the limit of the Kashaev invariant
  • related with the colored Jones polynomial

optimistic limit

  • volume conjecture
  • idea of the optimistic limit


examples

  • $4_1$ figure eight knot
  • $5_2$
  • $6_1$


known examples

  • figure eight knot
  • Borromean ring
  • torus knots
  • whitehead chains
  • all links of zero volume
  • twist knows is (almost) done


history

  • 1995 Kashaev constructed knot invariants $\langle K \rangle_N$
  • 1997 Kashaev proposed that the asymptotic behaviour of the 1995 invariant involves the volume of the hyperbolic 3-manifold
  • 2001 [MM01] Murakami-Murakami found that $\langle K \rangle_N$ can be obtained from evaluating the colored Jones polynomial at the $N$-th root of unity
