8 Jul 1999 | | Journal: | Nucl.Phys. B568 (2000) 457-471 | | Subject: | hep-th | | Affiliation: | Mainz) and Gerhard Weigt (DESY Zeuthen | | Abstract: | Gauged WZNW models are integrable conformal field theories. We integrate the classical slu{} theory with periodic boundary conditions, which describes closed strings moving in a curved target-space geometry. We calculate its Poisson bracket structure by solving an initial state problem. The results differ from previous field-theoretic calculations due to zero modes. For a future exact canonical quantization the physical fields are (non-locally) transformed onto canonical free fields. | | Source: | arXiv, hep-th/9907057 | | Services: | Forum | Review | PDF | Favorites | |
