Logarithmic operators in SL ( 2 , IR ) WZNW model , Singletons and AdS 3 / ( L ) CFT 2 correspondence

چکیده
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 > − 1 2 .

We discuss the relation between singletons in AdS 3 and logarithmic operators in the CFT on the boundary. In 2 dimensions there can be more logarithmic operators apart from those which correspond to singletons in AdS, because logarithmic operators can occur when the dimensions of primary fields differ by an integer instead of being equal. These operators may be needed to account for the greybod...

متن کاملLogarithmic CFT on the Boundary and the World-Sheet
The correspondences between logarithmic operators in the CFTs on the boundary of AdS3 and on the world-sheet and dipole fields in the bulk are studied using the free field formulation of the SL(2, C)/SU(2) WZNW model. We find that logarithmic operators on the boundary are related to operators on the world-sheet which are in indecomposable representations of SL(2). The Knizhnik-Zamolodchikov equ...
