Logarithmic tensor category theory, III: Intertwining maps and tensor
product bifunctors    [PDF]

Yi-Zhi Huang, James Lepowsky, Lin Zhang

This is the third part in a series of papers in which we introduce and develop a natural, general tensor category theory for suitable module categories for a vertex (operator) algebra. In this paper (Part III), we introduce and study intertwining maps and tensor product bifunctors.
