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

Let E\mathscr{E} be the category formed by the W ⁣A20(2)W^0_{\!A_2}(2)-modules obtained by decomposing the L32(sl3)L_{-\frac{3}{2}}(\mathfrak{sl}_3)-modules in D\mathscr{D}. 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, and let Eλ(8)E_{\lambda}^{(8)} and Mφ(λ)+ρM_{\varphi(\lambda)+\rho} denote the corresponding modules. Partial Kazhdan–Lusztig correspondence. The category E\mathscr{E} forms a vertex tensor category, and the identification of Eλ(8)E_{\lambda}^{(8)} with Mφ(λ)+ρM_{\varphi(\lambda)+\rho} partially defines a braided tensor equivalence between E\mathscr{E} and CR\mathscr{C}_{\mathbb{R}}. This is explicitly presented as a partial correspondence, while the later statement proposes its extension to all of CR\mathscr{C}_{\mathbb{R}}; no resolution is supplied.
