introduction

  • hyperbolic 3-manifold
  • three simple hyperbolic knots
    • \(4_{1}\) figure 8 knot
    • \(5_{2}\)
    • \(6_{1}\), \(6_{1}\), \(6_{1}\)

 

 

 

volume of figure eight knot complement

  • obtained by glueing two copies of ideal tetrahedra
  • thus the volume is given by
    \(6\Lambda(\pi/3)\) where 로바체프스키 함수
  • 2.02988321281930725
    \(V(4_{1})=\frac{9\sqrt{3}}{\pi^2}\zeta_{\mathbb{Q}(\sqrt{-3})}(2)=3D(e^{\frac{2i\pi}{3}})=2D(e^{\frac{i\pi}{3}})=2.029883212819\cdots\)
    where D is Bloch-Wigner dilogarithm.
  • what is \(\zeta_{\mathbb{Q}(\sqrt{-3})}(2)\)? numrically 1.285190955484149
  1. L[x_] := Im[PolyLog[2, x]] + 1/2 Log[Abs[x]] Arg[1 - x]
    f[x_, y_] :=
     L[x] + L[1 - x*y] + L[y] + L[(1 - y)/(1 - x*y)] + L[(1 - x)/(1 - x*y)]
    Print["five term relation"]
    Table[f[i, j], {i, 0.1, 0.9, 0.1}, {j, 0.1, 0.9, 0.1}] // TableForm

    N[2 L[Exp[I*Pi/3]], 20]
    N[3 (L[Exp[2 I*Pi/3]] - L[Exp[4 I*Pi/3]])/2, 20]
