Full Kazhdan–Lusztig correspondence for W ⁣A20(2)W^0_{\!A_2}(2)

Let E\mathscr{E} be the vertex tensor category of W ⁣A20(2)W^0_{\!A_2}(2)-modules obtained by decomposing the relevant L32(sl3)L_{-\frac{3}{2}}(\mathfrak{sl}_3)-modules, and let CR\mathscr{C}_{\mathbb{R}} be the full subcategory of finite-dimensional weight UiH ⁣(sl3)\overline{\mathcal{U}}{}_{\mathsf{i}}^H\!(\mathfrak{sl}_3)-modules with real weights. For generic λ\lambda and the specified parameter regions, use the modules Eλ(d)E_{\lambda}^{(d)}, Lφ(λ)+ρ(d)L_{\varphi(\lambda)+\rho}^{(d)}, and Lφ(λ)(d)L_{\varphi(\lambda)}^{(d)} appearing below. Full Kazhdan–Lusztig correspondence. There is a braided tensor equivalence between E\mathscr{E} and CR\mathscr{C}_{\mathbb{R}} defined by the displayed assignments for d=8,4,3,3,1d=8,4,3,\overline{3},1, with the exact genericity and parameter conditions stated in the source. The proposed equivalence extends the partial correspondence to atypical modules of degrees 11, 33, 44, and 88; the supplied text does not give evidence that it has been proved or refuted.
