Logarithmic tensor product theory for generalized modules for a conformal vertex algebra
Yi-Zhi Huang, James Lepowsky, Lin Zhang
We generalize the tensor product theory for modules for a vertex operator algebra previously developed in a series of papers by the first two authors to suitable module categories…

Vertex tensor category structure on a category of Kazhdan--Lusztig
Lin Zhang
We incorporate a category of certain modules for an affine Lie algebra, of a certain fixed non-positive-integral level, considered by Kazhdan and Lusztig, into the representation t…

On the concepts of intertwining operator and tensor product module in vertex operator algebra theory
Yi-Zhi Huang, James Lepowsky, Haisheng Li +1
We produce counterexamples to show that in the definition of the notion of intertwining operator for modules for a vertex operator algebra, the commutator formula cannot in general…
