# Generalized metric formulation of double field theory

@article{Hohm2010GeneralizedMF, title={Generalized metric formulation of double field theory}, author={Olaf Hohm and Christopher M. Hull and Barton Zwiebach}, journal={Journal of High Energy Physics}, year={2010}, volume={2010}, pages={1-35} }

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… Expand
