Irreducible knot-state asymptotics

At least 14 years old · documented by

Let KK be a knot with exterior EKE_K and peripheral torus Σ\Sigma. Let Ms(Σ){\mathcal M}^s(\Sigma) and Ms(EK){\mathcal M}^s(E_K) denote the smooth loci of the corresponding character moduli spaces, and let r:M(EK)→M(Σ)r:{\mathcal M}(E_K)\to{\mathcal M}(\Sigma) be restriction. For an open set U⊂Ms(Σ)U\subset{\mathcal M}^s(\Sigma), set V=r−1(U)V=r^{-1}(U) and assume that VV is connected, contained in Ms(EK){\mathcal M}^s(E_K), and that r∣Vr|_V is an embedding. Irreducible knot-state asymptotics conjecture. On UU,

Zk(EK)=eimπ/4k3/44π3/4Fkf(⋅,k)+O(k−∞),Z_k(E_K)=e^{i m\pi/4}\frac{k^{3/4}}{4\pi^{3/4}}F^k f(\mathord\cdot,k)+O(k^{-\infty}),

where mm is an integer, FF is a section of L→UL\to U satisfying F(r(ρ))=CS⁡(ρ)F(r(\rho))=\operatorname{CS}(\rho) for ρ∈V\rho\in V and the Cauchy–Riemann equation up to a term vanishing to infinite order along r(Ms)r({\mathcal M}^s), and f(⋅,k)f(\mathord\cdot,k) has an asymptotic expansion f0+k−1f1+⋯f_0+k^{-1}f_1+\cdots with coefficients in C∞(U,δ){\mathcal C}^{\infty}(U,\delta) satisfying (r∗φ(f02))(ρ)=±T(ρ)\bigl(r^*\varphi(f_0^2)\bigr)(\rho)=\pm\mathbb T(\rho). The conjecture gives the expected Chern–Simons phase and Reidemeister-torsion symbol near regular irreducible representations; the supplied text does not state a general resolution.
