The logarithmic module-count conjecture for the triplet vertex algebra

At least 16 years old · documented by

Let p,p′∈Z>0p,p'\in\mathbb{Z}_{>0} with p≠p′p\ne p' and p≥2p\geq 2. Let L=ZαL=\mathbb{Z}\alpha satisfy ⟨α,α⟩=2pp′\langle\alpha,\alpha\rangle=2pp', and let W(p,p′)\mathcal{W}(p,p') be the vertex operator algebra defined as the intersection of the kernels of the two screening operators associated with this lattice construction. The logarithmic module-count conjecture. The vertex algebra W(p,p′)\mathcal{W}(p,p') is C2C_2-cofinite and has 2pp′+(p−1)(p′−1)22pp'+\frac{(p-1)(p'-1)}{2} inequivalent irreducible modules. This conjecture concerns the finiteness and representation theory of the logarithmic minimal-model-type vertex algebra; the supplied text does not state whether it has been resolved.
