Relative Reshetikhin–Turaev volume conjecture with adjoint torsion

From papers

Let MM be a closed oriented 33-manifold and let LL be a framed hyperbolic link in MM with L|L| components. Let \\{\mathbf a^{(r)}\} be a sequence of colorings of the components of LL by obreak{0,,r2} obreak\{0,\dots,r-2\}, and define signs μk\mu_k and cone angles

θk(r)=μk(4πak(r)r2π).\theta^{(r)}_k=\mu_k\left(\frac{4\pi a^{(r)}_k}{r}-2\pi\right).

Assume that the corresponding hyperbolic cone metrics M(r)M^{(r)} exist for all sufficiently large rr, with volume Vol(M(r))\mathrm{Vol}(M^{(r)}), Chern–Simons invariant CS(M(r))\mathrm{CS}(M^{(r)}), logarithmic holonomies uγk(r)\mathbf u^{(r)}_{\gamma_k}, holonomy representation ρM(r)\rho_{M^{(r)}}, and adjoint Reidemeister torsion T(ML,m)([ρM(r)])\mathbb{T}_{(M{\smallsetminus} L,\mathbf m)}([\rho_{M^{(r)}}]). Relative Reshetikhin–Turaev volume conjecture. If {θ(r)}\{\theta^{(r)}\} converges as rr\to\infty, then, for all positive odd integers rr and q=e2πi/rq=e^{2\pi i/r},

RTr(M,L,a(r))=ce12k=1Lμkuγk(r)T(ML,m)([ρM(r)])er4π(Vol(M(r))+iCS(M(r)))(1+O(1r)),\mathrm{RT}_r(M,L,\mathbf a^{(r)})=c\frac{e^{\frac12\sum_{k=1}^{|L|}\mu_k\mathbf u^{(r)}_{\gamma_k}}}{\sqrt{\mathbb{T}_{(M{\smallsetminus} L,\mathbf m)}([\rho_{M^{(r)}}])}}e^{\frac{r}{4\pi}(\mathrm{Vol}(M^{(r)})+i\mathrm{CS}(M^{(r)}))}\left(1+O\left(\frac1r\right)\right),

where cc has norm 11 and is independent of the geometric structure on MM. This predicts an asymptotic expansion of relative Reshetikhin–Turaev invariants in terms of geometric data and adjoint torsion; it generalizes volume-conjecture phenomena. The source states that it was proved for special families, while the full assertion is not resolved here.
