Universal quantum modularity conjecture for geometric integer homology spheres

Let MN/π1(M)M\cong N/\pi_1(M) be a geometric integer homology sphere with model geometry NN, and let WM(ξ)W_M(\xi) be its properly normalized Witten–Reshetikhin–Turaev invariant for a primitive root of unity ξ\xi of odd order. Take ξ=e2πisr\xi=e^{\frac{2\pi i s}{r}} with r2Z1+1r\in 2\mathbb Z_{\geq 1}+1 and s4Z+1s\in 4\mathbb Z+1. Write ξ~=e2πirs\tilde\xi=e^{-\frac{2\pi i r}{s}}, let CS[A]\operatorname{CS}[A] denote the Chern–Simons invariant of a flat connection, and let AA_* be the geometric flat connection induced by the geometric structure. Universal quantum modularity conjecture. As r+r\to+\infty through integers coprime with ss,

WM(ξ)Aπ0(Hom(π1(M),SL(2,C)))e2πirsCS[A]PA(ξ~)IA(sr),W_M(\xi)\simeq\sum_{A\in\pi_0(\operatorname{Hom}(\pi_1(M),SL(2,\mathbb C)))}e^{2\pi i\frac{r}{s}\operatorname{CS}[A]}P_A(\tilde\xi)I_A\left(\frac{s}{r}\right),

where PA(ξ~)Z[ξ~]P_A(\tilde\xi)\in\mathbb Z[\tilde\xi] and IA(s/r)(s/r)δA/2Cs/rI_A(s/r)\in(s/r)^{\delta_A/2}\mathbb C\llbracket s/r\rrbracket for some δAZ\delta_A\in\mathbb Z; moreover,

PA(ξ)=ξδWM(ξ)+CN,P_{A_*}(\xi)=\xi^\delta W_M(\xi)+C_N,

with δZ\delta\in\mathbb Z and CN=1C_N=-1 if N=S3N=S^3, while CN=0C_N=0 otherwise. This extends quantum modularity from hyperbolic manifolds to geometric 3-manifolds and predicts that WRT asymptotics decompose into contributions from flat connections. The supplied text presents it as a conjecture but gives no resolution evidence.
