Kazhdan–Lusztig correspondence conjecture for (1,p)(1,p) logarithmic models

Let pp be the parameter of the (1,p)(1,p) logarithmic model, let W(p)\mathcal{W}(p) denote its representation category, and let Uqs(2)\overline{\mathscr{U}}_{\mathfrak{q}}s\ell(2) be the restricted quantum group with

q=eiπp.\mathfrak{q}=e^{\frac{i\pi}{p}}.

Kazhdan–Lusztig correspondence conjecture. The category of W(p)\mathcal{W}(p)-representations is equivalent to the category of finite-dimensional Uqs(2)\overline{\mathscr{U}}_{\mathfrak{q}}s\ell(2)-representations. The conjecture concerns the categorical correspondence for the (1,p)(1,p) logarithmic models; unlike the semisimple case, it requires no semisimplification on the quantum-group side. The source states that this issue remains to be addressed.
