内容摘要:
Tensor categories of vertex operator algebras play an important role in representation theory of vertex operator algebras and conformal field theories. A central problem of tensor category theory is the existence of the vertex tensor category structure. We develop a few general methods to establish the existence of tensor structure on module categories for vertex operator algebras, based on Huang-Lepowsky-Zhang's logarithmic tensor category theory. As applications, we obtain the tensor structure of affine Lie algebras at various levels, affine Lie superalgebra gl(1|1) and the Virasoro algebra at all central charges.
