Solutions of the Master Virasoro Equation as Conformal Points of Perturbed WZNW Model
نویسنده
چکیده
It is shown that the master equation of the affine-Virasoro construction on the unitary affine algebra naturally emerges in the fusion algebra of the nonunitary level k WZNW model. Operators corresponding to solutions of the master equation are suitable for performing one-parametrical renormalizable perturbation around the given conformal nonunitary WZNW model. In the large |k| limit, the infrared fixed point of the renormalization group beta function is found. There are as many infrared conformal points as 12N(N + 1), where N is the total number of solutions of the master equation.

Conformal Invariance Of Interacting WZNW Models
We consider two level k WZNW models coupled to each other through a generalized Thirring-like current-current interaction. It is shown that in the large k limit, this interacting system can be presented as a two-parameter perturbation around a nonunitary WZNW model. The perturbation operators are the sigma model kinetic terms with metric related to the Thirring coupling constants. The renormali...
متن کاملThe WZNW Model As An Integrable Perturbation Of The Witten Conformal Point
We show that the WZNW model with arbitrary σ-model coupling constant may be viewed as a σ-model perturbation of the WZNW theory around the Witten conformal point. In order for the σ-model perturbation to be relevant, the level k of the underlying affine algebra has to be negative. We prove that in the large |k| limit the perturbed WZNW system with negative k flows to the conformal WZNW model wi...
متن کاملConformal Non-Abelian Thirring Models
The Lie-Poisson structure of non-Abelian Thirring models is discussed and the Hamiltonian quantization of these theories is carried out. The consistency of the Hamiltonian quantization with the path integral method is established. It is shown that the space of non-Abelian Thirring models contains the nonperturbative conformal points which are in one-to-one correspondence with general solutions ...

The WZNW model at the Witten conformal point is perturbed by the σ-model term. It is shown that in the large level k limit the perturbed WZNW system with negative k arrives at the WZNW model with positive k.
متن کاملExact C - Function and C - Theorem on Affine - Virasoro Space ∗
An exact C-function, which is an action for the Virasoro master equation, is obtained on affine-Virasoro space. The solutions of the master equation are fixed points of an associated flow, which obeys a C-theorem. The closed sub-flow SO(n)diag is a flow on the space of graphs, and the associated Morse polynomials are known generating functions in graph theory. The general flow also implies a me...
