Chern-Simons Gauge Theory and Knot Polynomial Invariants — E8 Intelligence Research

FINDING: Chern-Simons gauge theory with gauge group G and level k produces knot invariants as vacuum expectation values of Wilson loops; the Jones polynomial is the SU(2) case at k=1, and the HOMFLY polynomial arises from SU(N) at arbitrary k. MATH: - Chern-Simons action: S_CS = (k/4π) ∫_M Tr(A ∧ dA + (2/3)A ∧ A ∧ A) - Wilson loop: W_R(C) = Tr_R [P exp(∮_C A_μ dx^μ)] - Partition function: Z(M) = ∫ DA exp(iS_CS), giving knot invariants ⟨W_R(C)⟩ = V_R(q) with q = exp(2πi/(k+h^∨)), h^∨ = dual Coxeter number - For SU(2): h^∨ = 2, so q = exp(2πi/(k+2)) - Jones polynomial: V(t) with t = q (at k=1, SU(2)) - HOMFLY: P(a,z) from SU(N) with a = q^N, z = q − q^{-1} - Kauffman polynomial: from SO(N)/Sp(N) groups - Quantum group: U_q(sl_2) with [n]_q = (q^n − q^{-n})/(q − q^{-1}) - R-matrix: Ř = q^{1/2} Σ e_i⊗e^i + (q^{1/2} − q^{-1/2}) Σ_{i Author: Andrew Stewart Caldin, Independent Researcher, UK.
