MARGINAL DEFORMATIONS OF WZNW AND COSET MODELS FROM O ( d , d ) TRANSFORMATION
We show that O(2, 2) transformation of SU(2) WZNW model gives rise to marginal deformation of this model by the operator d 2 zJ(z) ¯ J (¯ z) where J, ¯ J are U(1) currents in the Cartan subalgebra. Generalization of this result to other WZNW theories is discussed. We also consider O(3, 3) transformation of the product of an SU(2) WZNW model and a gauged SU(2) WZNW model. The three parameter set...
متن کاملD ec 1 99 5 Gauged WZNW models and coset constructions in relation to string theories .
Preface I will begin by a few words on the layout of this thesis. At the end of each chapter I give the main sources of information on the subject dealt with, and at the very end of the first part there is a more complete set of references. I do not claim to include all relevant references, and I apologize if someone has been left out. This thesis consists of two parts, first an introduction to...
متن کاملMarginal Deformations from Branes
We study brane configurations for four dimensionalN=1 supersymmetric gauge theories with quartic superpotentials which flow in the infrared to manifolds of interacting superconformal fixed points. We enumerate finite N=2 theories, from which a large class of marginal N=1 theories descend. We give the brane descriptions of these theories in Type IIA and Type IIB string theory. The Type IIB descr...
متن کاملOperator quantization of constrained WZNW theories and coset constructions. A.V.Bratchikov
Operator quantization of constrained WZNW theories and coset constructions. Abstract Using two WZNW theories for Lie algebras g and h, h ⊂ g, we construct the associative quotient algebra which includes a class of g/h coset primary fields and currents. 1. In a recent article [1] for generic g/h coset conformal field theory [2] a class of Virasoro primary fields and currents was constructed.They...
متن کاملOperator Quantization of Constrained Wznw Theories and Coset Constructions
Operator quantization of the WZNW theory for Lie algebra g with constrained affine Lie algebrâ h, h ⊂ g, is performed.The extended phase space and effective first class constraints are constructed which determine a class of g/h coset primary fields and currents. In a recent article [1] for generic g/h coset conformal field theory [2, 3] a class of Virasoro currents and primary fields was constr...
