introduction
  • volume of knot complements
  • Chern-Simons invariant of manifolds
  • Turaev-Viro invariant (related to 6j symbols)
    • Kauffman and Line 'The Temperley Lie algebra recoupling theory and invariants of 3-manifolds"
    • Turaev-Viro "state sum invariants of 3-manifolds and quantum 6j-symbols)

 

 

==maps between threefolds

  • maps between aspherical 3 manifolds
  • aspherical threefolds = second and higher homotopy groups vanish
  • JSJ decomposition http://en.wikipedia.org/wiki/JSJ_decomposition
    • cutting M into
      • Seifert fibered pieces ~ non hyperbolic pieces
      • atoroidal pieces ~ hyperbolic pieces
  • Thurston's geometrization
    • S^3, E\times S^2, Sol
    • E^3, E\times H^2, SL_2
    • H^3, Nil

 

 

Volume of knot complement
  1. KnotData[]
    KnotData["FigureEight", "HyperbolicVolume"]
    N[%, 20]
  • Dedekind zeta funciton evaluated at 2 gives a number related to volume of 3-manifold
  • Bloch-Wigner dilogarithm is involved

 

 

a problem
  • Prove
    \(\frac{24}{7\sqrt{7}}\int_{\pi/3}^{\pi/2}\ln|\frac{\tan t+\sqrt{7}}{\tan t-\sqrt{7}}|\,dt=\frac{2}{\sqrt{7}}(D(e^{2\pi i/7})+D(e^{4\pi i/7})-D(e^{6\pi i/7}))=\frac{2}{\sqrt{7}}(Cl(2\pi /7})+Cl(4\pi/7})-Cl(6\pi/7}))\)
  • a log tangent integral
