Non-compact String Backgrounds and Non-rational CFT | Volker Schomerus
; | Date: |
20 Sep 2005 | Subject: | hep-th | Abstract: | This is an introduction to the microscopic techniques of non-rational bulk and boundary conformal field theory which are needed to describe strings moving in non-compact curved backgrounds. The latter arise e.g. in the context of AdS/CFT-like dualities and for studies of time-dependent processes. After a general outline of the central concepts, we focus on two specific but rather prototypical models: Liouville field theory and the 2D cigar. Rather than following the historical path, the presentation attempts to be systematic and self-contained. | Source: | arXiv, hep-th/0509155 | Services: | Forum | Review | PDF | Favorites |
