We derive a formula for expressing free cumulants whose entries are products of random variables in terms of the lattice structure of non-crossing partitions. We show the usefulness of that result by giving direct and conceptually simple proofs for a lot of results about R-diagonal elements. Our inv

Fusion rules among irreducible modules for the free bosonic orbifold vertex operator algebra are completely determined.
Rational vertex operator algebras, which play a fundamental role in rational conformal field theory (see [BPZ and MS]), single out an important class of vertex operator algebras. Most vertex operator algebras which have been studied so far are rational vertex operator algebras. Familiar examples inc
