T-duality, pure spinors and non geometric backgrounds
Michela Petrini (LPTHE)
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
