Yang–Wong volume conjecture for relative Reshetikhin–Turaev invariants

Let MM be a closed oriented 33-manifold and let LL be a framed hyperbolic link in MM with nn components. For odd integers r3r\geq 3, let m=(m1,,mn)\mathbf m=(m_1,\dots,m_n) and let RTr(M,L,m)RT_r(M,L,\mathbf m) be the rr-th relative Reshetikhin–Turaev invariant of MM with LL colored by m\mathbf m, evaluated at q=e2π1rq=e^{\frac{2\pi\sqrt{-1}}{r}}. For a sequence m(r)=(m1(r),,mn(r))\mathbf m^{(r)}=(m_1^{(r)},\dots,m_n^{(r)}), define

θk=2πlimr4πmk(r)r,θ=(θ1,,θn).\theta_k=\left\lvert 2\pi-\lim_{r\to\infty}\frac{4\pi m_k^{(r)}}{r}\right\rvert,\qquad \theta=(\theta_1,\dots,\theta_n).

If MLθM_{L_\theta} is the hyperbolic cone manifold consisting of MM equipped with a hyperbolic cone metric whose singular locus is LL and whose cone angles are θ\theta, then Yang–Wong's volume conjecture.

limr4πrlogRTr(M,L,m(r))=Vol(MLθ)+1CS(MLθ),\lim_{r\to\infty}\frac{4\pi}{r}\log RT_r(M,L,\mathbf m^{(r)})=\operatorname{Vol}(M_{L_\theta})+\sqrt{-1}\operatorname{CS}(M_{L_\theta}),

where rr ranges over all positive odd integers. This conjecture predicts that the asymptotics of the relative invariants recover the hyperbolic volume and Chern–Simons invariant of the associated cone manifold. The paper verifies the leading-order term for pairs whose link complements are fundamental shadow link complements after suitable rational Dehn fillings, under additional assumptions on surgery denominators and sufficiently small cone angles.
