Semikhatov–Tipunin's logarithmic Kazhdan–Lusztig correspondence conjecture

Let VV be one of the vertex algebras specified by the paper's extension pairs, let AA be the corresponding free field algebra, and let N\mathfrak{N} be the Nichols algebra generated by the screening operators inside Repwt(A)\mathrm{Rep}^{\mathrm{wt}}(A). Semikhatov–Tipunin's conjecture. (1) The category Repwt(V)\mathrm{Rep}^{\mathrm{wt}}(V) has a braided tensor structure in the sense of Huang–Lepowsky–Zhang and

Repwt(V)NNYD(Repwt(A))\mathrm{Rep}^{\mathrm{wt}}(V)\simeq {}^{\mathfrak{N}}_{\mathfrak{N}}\mathcal{YD}(\mathrm{Rep}^{\mathrm{wt}}(A))

as braided tensor categories. (2) For V=sMp(sl21)V=s\mathcal{M}_p(\mathfrak{sl}_{2|1}),

Repwt(sMp(sl21))Repwt(uqH(sl21)).\mathrm{Rep}^{\mathrm{wt}}(s\mathcal{M}_p(\mathfrak{sl}_{2|1}))\simeq\mathrm{Rep}^{\mathrm{wt}}(u_q^H(\mathfrak{sl}_{2|1})).

This is the proposed logarithmic Kazhdan–Lusztig correspondence for these vertex algebras; the source does not state that it has been resolved.
