Gorsky–Neguț–Rasmussen conjecture on coherent computation of Khovanov–Rozansky homology

Let FβF_\beta be the Rouquier complex associated to a braid β\beta, let Tn\mathcal{T}_n be the tautological bundle on the dg flag Hilbert scheme, and let ι\iota_* and ι\iota^* be the adjoint functors in the preceding conjecture. Write \int for pushforward to a point in the coherent equivariant category.

Gorsky–Neguț–Rasmussen conjecture. There is an isomorphism of bigraded vector spaces

HHHk(Fβ)HH0(ι(kTn)Fβ)ι(Fβ)kTn.\operatorname{HHH}^{k}(F_\beta)\simeq\operatorname{HH}^{0}\bigl(\iota^*(\wedge^k\mathcal{T}_n^{\vee})\otimes F_\beta\bigr)\simeq\int \iota_*(F_\beta)\otimes\wedge^k\mathcal{T}_n^{\vee}.

The proposed formula would compute Khovanov–Rozansky homology on the coherent side of the flag-Hilbert-scheme model. The paper describes it as a prediction from the cited conjecture, not as a theorem.
