Abelian knot-state asymptotics

Let KK be a knot with exterior EKE_K, let E=H1(Σ,R)E=H_1(\Sigma,\mathbb R) for the peripheral torus Σ\Sigma, and let λ\lambda be the longitude direction. Let a regular point of Rλ\mathbb R\lambda mean a point satisfying the source's condition that a neighborhood of its image avoids irreducible representations and that the Alexander polynomial does not vanish at the corresponding point. Abelian knot-state asymptotics conjecture. Every regular point of Rλ\mathbb R\lambda has an open neighborhood VEV\subset E such that VRλV\cap\mathbb R\lambda consists of regular points and

Zk(EK)(x)=eimπ/4(k2π)1/4tλk(x)f(x,k)Ωλ+O(k),xV,Z_k(E_K)(x)=e^{i m\pi/4}\left(\frac{k}{2\pi}\right)^{1/4}t_\lambda^k(x)\otimes f(x,k)\Omega_\lambda+O(k^{-\infty}),\qquad x\in V,

where mm is an integer, tλt_\lambda is the holomorphic section of LEL\to E restricting to 11 on Rλ\mathbb R\lambda, f(,k)f(\mathord\cdot,k) has an asymptotic expansion f0+k1f1+f_0+k^{-1}f_1+\cdots,

f0(qλ)=12σσ1ΔK(σ2),σ=e2πiq,f_0(q\lambda)=\frac{1}{\sqrt2}\frac{\sigma-\sigma^{-1}}{\Delta_K(\sigma^2)},\qquad \sigma=e^{2\pi i q},

and Ωλδ\Omega_\lambda\in\delta satisfies Ωλ2(λ)=1\Omega_\lambda^2(\lambda)=1. This conjecture describes the leading asymptotics near regular abelian representations; the supplied text gives no resolution status.
