We define automorphisms of vertex operator algebra using the representations of the Virasoro algebra. In particular, we show that the existence of a special 1 element, which we will call a ''rational conformal vector with central charge ,'' 2 implies the existence of an automorphism of a vertex oper
We will prove the Borwein identity by computing the characters of some automorphisms of the lattice vertex operator algebra (VOA) of type E 6 . As similar examples, we will prove two identities containing the famous Jacobi identity, which was also obtained from the VOA of type D 4 by Frenkel Lepowsk

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
