本文给出了C ~ 2-上有限顶点算子代数V的C ~ 2-上有限性的一个充要条件,并给出了V的2-圈置换σ。作为应用,我们证明了具有最小中心电荷的单Virasoro顶点算子代数L(c,0)的2-圈置换轨道模型是C ~ 2-余有限的.
In this article, we give a sufficient and necessary condition for theC2-cofiniteness offor aC2-cofinite vertex operator algebraVand the 2-cycle permutationσof. As an application, we show that the 2-cycle permutation orbifold model of the simple Virasoro vertex operator algebraL(c, 0) of minimal central chargecisC2-cofinite.
