Abstract

We introduce a category of bounded modules for the full toroidal Lie algebras. Using the fact that the full toroidal algebras are vertex Lie algebras, we construct the toroidal vertex operator algebra. This VOA controls the representation theory of toroidal Lie algebras, and every irreducible module in the category of bounded modules is a simple module for the toroidal VOA. This allows us to give explicit realizations for the irreducible bounded modules and find their characters.
