Hecke lifting conjecture for framed links

Let cmathcalLcmathcal{L} be a framed oriented link in S3S^3 with framing cvecctau=(ctau1,,ctauL)cvec{ctau}=(ctau^1,\cdots,ctau^L). For a partition cmucmu, let cZcmu(cmathcalL;q,a)cZ_{cmu}(cmathcal{L};q,a) be the reformulated framed colored HOMFLY-PT invariant, let ccheckcZcmu=cbracecmucZcmuccheck{cZ}_{cmu}=cbrace{cmu}cZ_{cmu}, and let cPsip(f(q,a))=f(qp,ap)cPsi_p(f(q,a))=f(q^p,a^p) be the Adams operator. Write AcequivBcmodCAcequiv Bcmod C when (AB)/CcincmathbbZ[z2,acpm1](A-B)/Ccincmathbb{Z}[z^2,a^{cpm1}], where z=qq1z=q-q^{-1} and [p]=(qpqp)/(qq1)[p]=(q^p-q^{-p})/(q-q^{-1}). Hecke lifting conjecture. For any prime number pp,

Zˇp(L;q,a)(1)(p1)α=1LταΨp(Zˇ(L;q,a))mod[p]2.\check{\mathcal{Z}}_{p}(\mathcal{L};q,a)\equiv (-1)^{(p-1)\sum_{\alpha=1}^L\tau^\alpha} \Psi_p(\check{\mathcal{Z}}(\mathcal{L};q,a)) \mod [p]^2.

This conjecture is a proposed integrality and congruence property for reformulated colored HOMFLY-PT invariants, motivated by the Chern-Simons/topological-string duality. The supplied text does not state whether this general framed-link version has been proved or disproved.
