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…
