Generalized metric formulation of double field theory

| Summary: | The generalized metric is a T-duality covariant symmetric matrix constructed from the
metric and two-form gauge field and arises in generalized geometry. We view it here as
a metric on the doubled spacetime and use it to give a simple formulation with manifest
T-duality of the double field theory that describes the massless sector of closed strings.
The gauge transformations are written in terms of a generalized Lie derivative whose
commutator algebra is defined by a double field theory extension of the Courant bracket. |
