Book DetailsMemoirs of the American Mathematical SocietyVolume: 106; 1993; 85 ppMSC: Primary 17
This book extends the Jacobi identity, the main axiom for a vertex operator algebra, to multioperator identities. Based on constructions of Dong and Lepowsky, relative \({\mathbf Z}_2\)twisted vertex operators are then introduced, and a Jacobi identity for these operators is established. Husu uses these ideas to interpret and recover the twisted Z operators and corresponding generating function identities developed by Lepowsky and Wilson for the construction of the standard \(A^{(1)}_1\)modules. The point of view of the Jacobi identity also shows the equivalence between these twisted Zoperator algebras and the (twisted) parafermion algebras constructed by Zamolodchikov and Fadeev. The LepowskyWilson generating function identities correspond to the identities involved in the construction of a basis for the space of Cdisorder fields of such parafermion algebras.
ReadershipMathematicians and physicists interested in vertex operators, Lie theory, conformal field theory, and string theory.
