Wk structure of generalized Frenkel-Kac construction for SU(2)-level k Kac-Moody algebra
نویسنده
چکیده
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 boson compactified on a circle.

Stress-Tensor for parafermions by the generalized Frenkel-Kac construction of affine algebras
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...

متن کاملThe two parameter quantum groups $U_{r,s}(mathfrak{g})$ associated to generalized Kac-Moody algebra and their equitable presentation
We construct a family of two parameter quantum grou-\ps $U_{r,s}(mathfrak{g})$ associated with a generalized Kac-Moody algebra corresponding to symmetrizable admissible Borcherds Cartan matrix. We also construct the $textbf{A}$-form $U_{textbf{A}}$ and the classical limit of $U_{r,s}(mathfrak{g})$. Furthermore, we display the equitable presentation for a subalgebra $U_{r...
متن کاملRoot multiplicities of hyperbolic Kac–Moody algebras and Fourier coefficients of modular forms
In this paper we consider the hyperbolic Kac–Moody algebra F associated with the generalized Cartan matrix ( 2 −2 0 −2 2 −1 0 −1 2 ) . Its connection to Siegel modular forms of genus 2 was first studied by A. Feingold and I. Frenkel. The denominator function of F is not an automorphic form. However, Gritsenko and Nikulin extended F to a generalized Kac–Moody algebra whose denominator function i...
متن کاملKac–Moody Symmetries of Critical Ground States
The symmetries of critical ground states of two-dimensional lattice models are investigated. We show how mapping a critical ground state to a model of a rough interface can be used to identify the chiral symmetry algebra of the conformal field theory that describes its scaling limit. This is demonstrated in the case of the six-vertex model, the three-coloring model on the honeycomb lattice, and...
