T-duality, pure spinors and non geometric backgrounds
18.09.2008 at 16:15
We discuss some properties of O(d,d) transformation, in particular T-duality, in the context of generalized geometry. We show how non-geometric backgrounds can be described in this context and propose a definition, based on the Courant bracket, of the charges f, H, Q and R appearing in effective four-dimensional theories.
