3-manifolds and their invariants

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
