Weigt: The complete solution of the classical SL(2, R)/U(1) gauged WZNW field theory

چکیده
We prove that any gauged WZNW model has a Lax pair representation, and give explicitly the general solution of the classical equations of motion of the SL(2,R)/U(1) theory. We calculate the symplectic structure of this solution by solving a differential equation of the Gelfand-Dikii type with initial state conditions at infinity, and transform the canonical physical fields non-locally onto canonical free fields. The results will, finally, be collected in a local Bäcklund transformation. These calculations prepare the theory for an exact canonical quantization. God does not care about our mathematical difficulties. He integrates empirically. Albert Einstein

Analytical Solution of the Sl(2,r)/u(1) Wznw Black Hole Model
The gauged SL(2,R)/U(1) Wess-Zumino-Novikov-Witten (WZNW) model is classically an integrable conformal field theory. We have found a Lax pair representation for the non-linear equations of motion, and a Bäcklund transformation. A second-order differential equation of the Gelfand-Dikii type defines the Poisson bracket structure of the theory, and its fundamental solutions describe the general so...
متن کاملIntegration of the SL(2,R)/U(1) Gauged WZNW Model with Periodic Boundary Conditions
Gauged WZNWmodels are integrable conformal field theories. We integrate the classical SL(2,R)/U(1) theory with periodic boundary conditions, which describes closed strings moving in a curved targetspace geometry. We calculate its Poisson bracket structure by solving an initial state problem. The results differ from previous fieldtheoretic calculations due to zero modes. For a future exact canon...
متن کاملIntegration of the SL(2,R)/U(1) Gauged WZNW Theory by Reduction and Quantum Parafermions
Using a gauge invariant reduction we directly integrate the SL(2,R)/U(1) WZNW theory. We prove that the conserved parafermions of this theory are coset currents. Quantum mechanically, the parafermion algebra, the energy-momentum tensor, and ‘auxiliary’ parafermions are deformed in a self-consistent manner.
متن کاملHeterotic string solutions and coset conformal field theories
Abstract We discuss solutions of the heterotic string theory which are analogous to bosonic and superstring backgrounds related to coset conformal field theories. A class of exact ‘left-right symmetric’ solutions is obtained by supplementing the metric, antisymmetric tensor and dilaton of the superstring solutions by the gauge field background equal to the generalised Lorentz connection with to...
متن کاملCausal Poisson Brackets of the SL(2,R) WZNW Model and its Coset Theories
From the basic chiral and anti-chiral Poisson bracket algebra of the SL(2, R) WZNW model, non-equal time Poisson brackets are derived. Through Hamiltonian reduction we deduce the corresponding brackets for its coset theories. The analysis of WZNWmodels is usually reduced to a separate treatment of its chiral or anti-chiral components [1, 2, 3]. But much simpler results can arise when the contri...
