Strong rationality equivalence for unitary minimal W-algebras

Let Wk(g,f)W_k(\mathfrak{g},f) be a unitary minimal WW-algebra, with corresponding conformal net denoted by AWk(g,f)\mathcal{A}_{W_k(\mathfrak{g},f)}. The algebra is strongly rational when it has the strong rationality properties used in the paper, and the conformal net is completely rational in the sense of conformal-net theory. Strong rationality equivalence conjecture.

Wk(g,f) is strongly rationalAWk(g,f) is completely rational.W_k(\mathfrak{g},f)\text{ is strongly rational}\quad\Longleftrightarrow\quad\mathcal{A}_{W_k(\mathfrak{g},f)}\text{ is completely rational}.

The theorem preceding this conjecture proves the equivalence for g{sl2,spo(21),spo(22),spo(23),psl(22)}\mathfrak{g}\in\{\mathfrak{sl}_2,\mathfrak{spo}(2|1),\mathfrak{spo}(2|2),\mathfrak{spo}(2|3),\mathfrak{psl}(2|2)\} or at a collapsing level, while the conjecture asks for the converse in all unitary minimal WW-algebras.
