Chern-Simons gauge theory and Witten's invariant

introduction

• 3D TQFT( Chern-Simons theory)
• CS is an invariant for 3-manifolds
• Kashaev Volume conjecture
• action
  Let \(A\) be a SU(2)-connection on the trivicla C^2 bundle over S^3
  \(S=\frac{k}{4\pi}\int_M \text{tr}\,(A\wedge dA+\tfrac{2}{3}A\wedge A\wedge A)=\frac{k}{4\pi}\int_M \text{tr}\,(A\wedge dA+\tfrac{1}{3}A\wedge [A,A])\)
  
• path integral gives Jones polynomials
  \(\langle K\rangle=\int {\operatorname{Tr}(\int_{K} A)}e^{2\pi i k \operatorname{CS}(A)}DA=(q^{1/2}+q^{-1/2})V(K,q^{-1})\)
  \(e^{2\pi i k \operatorname{CS}(A)}DA\): formal probability measure on the space of all connections, coming grom quantum field theory and the Chern-Simons action
  \({\operatorname{Tr}(\int_{K} A)}\) : measures the twisting of the connection along the knot
  

 

 

 

• curvature and parallel transport
• Chern class
• vector valued differential forms

 

 

M : threefold

\(P\to M\) : principal G-bundle

\(F=A\wedge dA+A\wedge A\)

\(\operatorname{det}(I+\frac{iF}{2\pi})= c_0+c_1+c_2\)

\(c_3=A\wedge dA+\tfrac{2}{3}A\wedge A\wedge A\)

\(c_2=\frac{1}{8\pi^2} \operatorname{tr} F\wedge F =dc_3\)

\(\int_M c_3\)

 

 

Morse theory approach

• Taubes, Floer interpret the Chern-Simons function as a Morse function on the space of all gauge fields modulo the action of the group of gauge transformations
• analogous to Euler characteristic of a manifold can be computed as the signed count of Morse indices
