Abstract: In this paper, we study the family of vertex operator algebras , known as symplectic fermions. This family is of a particular interest because these VOAs are irrational and -cofinite. We determine Zhu’s algebra and show that the equality of dimensions of and the -algebra holds for (the case of was treated by T. Abe in ). We use these results to prove a conjecture by Y. Arike and K. Nagatomo () on the dimension of the space of one-point functions on .
