Logarithmic operators in the SL(2, R) WZNW model
نویسنده
چکیده
We find some exact solutions of the Knizhnik-Zamolodchikov equation for the four point correlation functions that occur in the SL(2, R) WZNW model. They exhibit logarithmic behaviour in both the Kac-Moody and Virasoro parts. We discuss their implication for the operator product expansion. We also observe the appearance of several symmetries of the correlation functions. [email protected] [email protected]

We discuss the origin of logarithmic operators in AdS 3 string theory. It is shown that j = − 1 2 representation can give logarithmic correlation functions in the boundary CFT. Singletons play a special role in AdS 3 /CF T 2 correspondence as they also give logarithmic correlation functions in boundary CFT. For this one has to cross the j = − 1 2 barrier and define correlation functions for j >...
متن کاملOrigin of Logarithmic Operators in Conformal Field Theories
We study logarithmic operators in Coulomb gas models, and show that they occur when the “puncture” operator of the Liouville theory is included in the model. We also consider WZNW models for SL(2,R), and for SU(2) at level 0, in which we find logarithmic operators which form Jordan blocks for the current as well as the Virasoro algebra. e-mail: [email protected] e-mail: a.lewis1@phy...

متن کاملZamolodchikov relations and Liouville hierarchy in SL(2, R)k WZNW model
We study the connection between Zamolodchikov operator-valued relations in Liouville field theory and in the SL(2,R)k WZNW model. In particular, the classical relations in SL(2,R)k can be formulated as a classical Liouville hierarchy in terms of the isotopic coordinates, and their covariance is easily understood in the framework of the AdS3/CFT2 correspondence. Conversely, we find a closed expr...
