Construction of String Solutions around Non-trivial Backgrounds | Costas Kounnas
; | Date: |
14 Feb 1993 | Subject: | hep-th | Abstract: | We present a way of constructing string solutions around non-trivial gravitational backgrounds. The proposed solutions are constructed using $N = 4$ superconformal building blocks with $hat c = 4$. We give two different and inequivalent realizations of non-trivial four-dimensional subspaces, and we show the emergence of the $N = 4$ globally defined superconformal symmetry. The existence of $N = 4$ world-sheet symmetry stabilizes our solutions and implies in target space a number of covariantized supersymmetries around space-time dependent gravitational and dilaton backgrounds. | Source: | arXiv, hep-th/9302058 | Services: | Forum | Review | PDF | Favorites |
