Functorial colored knot homology conjecture

Let KK be a framed oriented knot, let Kar(T ⁣L)\operatorname{Kar}(\mathcal T\mkern-3mu\mathcal L)^\oplus be the additive Karoubi envelope of the Temperley–Lieb category, and let VnV_n denote the nn-th color with V1V_1 the fundamental color. Functorial colored knot homology conjecture. Each framed oriented knot KK determines a dg functor

C(K;):Ch(Kar(T ⁣L))Ch(κmod)C(K;-):\operatorname{Ch}^-(\operatorname{Kar}(\mathcal T\mkern-3mu\mathcal L)^\oplus)\longrightarrow\operatorname{Ch}^-(\kappa\mathrm{-mod})

such that C(K;V1n)C(K;V_1^{\otimes n}) is the quantum annular complex associated to the nn-cable of KK, and C(K;Vn)C(K;V_n) is a quantum annular version of Khovanov's colored sl2\mathfrak{sl}_2-homology. This is proposed as a functorial categorified Reshetikhin–Turaev construction; the supplied text says it is planned for future work and does not state that it has been proved.
