Stress-Tensor for parafermions from the generalized Frenkel-Kac construction of affine algebras
نویسنده
چکیده
I discuss a realization of stress-tensor for parafermion theories following the generalized Frenkel-Kac construction for higher level Kac-Moody algebras. All the fields are obtained from d=rank free bosons compactified on torus. This gives an alternative realization of Virasoro algebra in terms of a non-local correction of a free field construction which does not fit the usual background charge of Feigin-Fuchs approach.

متن کاملWk structure of generalized Frenkel-Kac construction for SU(2)-level k Kac-Moody algebra
Wk structure underlying the transverse realization of SU(2) at level k is analyzed. Extension of the equivalence existing between covariant and lightcone gauge realization of affine Kac-Moody algebra to Wk algebras is given. Higher spin generators related to parafermions are extracted from the operator product algebra of the generators and are showed to be written in terms of only one free boso...
متن کامل6 Generalized Kac - Moody Lie Algebras and Product Quivers
We construct the entire generalized Kac-Moody Lie algebra as a quotient of the positive part of another generalized Kac-Moody Lie algebra. The positive part of a generalized Kac-Moody Lie algebra can be constructed from representations of quivers using Ringel's Hall algebra construction. Thus we give a direct realization of the entire generalized Kac-Moody Lie algebra. This idea arises from the...
متن کاملVertex representations of quantum affine algebras.
We construct vertex representations of quantum affine algebras of ADE type, which were first introduced in greater generality by Drinfeld and Jimbo. The limiting special case of our construction is the untwisted vertex representation of affine Lie algebras of Frenkel-Kac and Segal. Our representation is given by means of a new type of vertex operator corresponding to the simple roots and satisf...
متن کاملTwo-sided Bgg Resolutions of Admissible Representations
We prove the conjecture of Frenkel, Kac and Wakimoto on the existence of two-sided BGG resolutions of G-integrable admissible representations of affine Kac-Moody algebras at fractional levels. As an application we establish the semi-infinite analogue of the generalized Borel-Weil theorem for minimal parabolic subalgebras which enables an inductive study of admissible representations.
