D-branes in Nongeometric Backgrounds | Albion Lawrence

2 Feb 2006 | Abstract: | "T-fold" backgrounds are generically nongeometric compactifications of string theory, described by T^n fibrations of a base N with transition functions in the perturbative T-duality group. We review Hull’s doubled torus formalism, which geometrizes these backgrounds, and use the formalism to constrain the D-brane spectrum (to leading order in g_s and alpha’) on T^n fibrations over S^1 with O(n,n;Z) monodromy. We also discuss the "D-geometry" of the moduli space of such branes, and argue that such a geometry is always geometric, and is a multiple or infinite cover of the T-fold. | Source: | arXiv, hep-th/0602025 | Services: | Forum | Review | PDF | Favorites |
