Extended SL ( 2 , R ) / U ( 1 ) characters , or modular properties of a simple non - rational conformal field theory

We define extended SL(2,R)/U(1) characters which include a sum over winding sectors. By embedding these characters into similarly extended characters of N = 2 algebras, we show that they have nice modular transformation properties. We calculate the modular matrices of this simple but non-trivial non-rational conformal field theory explicitly . As a result, we show that discrete SL(2,R) represen...

Algebraic approach to parafermionic conformal field theories

Parafermionic conformal field theories are considered on a purely algebraic basis. The generalized Jacobi type identity is presented. Systems of free fermions coupled to each other by nontrivial parafermionic type relations are studied in detail. A new parafermionic conformal algebra is introduced, it describes the sl(2|1)2/u(1) coset system.

An Infinite Number of Commuting Quantum ˆ W ∞ Charges in the SL(2, R)/U(1) Coset Model

The conformal non-compact SL(2, R)/U(1) coset model in two dimensions has been recently shown to embody a nonlinear Ŵ∞ current algebra, consisting of currents of spin ≥ 2 including the energy-momentum tensor. In this letter we explicitly construct an infinite set of commuting quantum Ŵ∞ charges in the model with k = 1. These commuting quantum charges generate a set of infinitely many compatible...

The Spectrum of Sl(2, R)/u(1) Black Hole Conformal Field Theory

We study string theory in the background of a two-dimensional black hole which is described by an SL(2, R)/U(1) coset conformal field theory. We determine the spectrum of this conformal field theory using supersymmetric quantum mechanics and give an explicit form of the vertex operators in terms of the Jacobi functions. We also discuss the applicability of SUSY quantum mechanics techniques to n...

Generalized abelian coset conformal field theories. Abstract Primary fields and correlation functions of an arbitrary abelian coset conformal field theory are explicitly expressed in terms of the associated W algebra and u(1) d currents.The coset theory has global abelian symmetry. In this paper we study conformal field theories based on the generalized coset construction [1-3] K(m) = L(m) − L ...
