متن کاملKnizhnik-Zamolodchikov-type equations for gauged WZNW models
We study correlation functions of coset constructions by utilizing the method of gauge dressing. As an example we apply this method to the minimal models and to the Witten 2D black hole. We exhibit a striking similarity between the latter and the gravitational dressing. In particular, we look for logarithmic operators in the 2D black hole. e-mail: [email protected] e-mail: a.lewis1@...
متن کاملOn the Gauged Non-compact Spin System
We examine classical and quantum aspects of the planar non-compact spin system coupled with Chern-Simons gauge field in the presence of background charge. We first define our classical spin system as non-relativistic non-linear sigma model in which the order parameter spin takes value in the non-compact manifold M = SU(1, 1)/U(1). Although the naive model does not allow any finite energy self d...
متن کاملWznw Models from Non-standard Bilinear Forms
We study the WZNW models based on nonstandard bilinear forms. We approach the problem from algebraic, perturbative and functional exact methods. It is shown that even in the case of integer k we can find irrational CFT’s. We prove that when the base group is noncompact with nonabelian maximal compact subgroup, the KacMoody representations are nonunitary.
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...
