报告摘要：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. 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.
