Intertwining operators,eory (see for example [FHL]), it is natural to consider “intertwining operators” parametrized by the vectors in a module, mapping one module to another. In this chapter, we discuss duality for intertwining operators associated with module elements against vertex operators associated with algebra ele

We identify the precise sense in which the notion of (ordinary) vertex operator algebra, i
