Abstract Finite gauge transformations in double field theory can be defined by the exponential of generalized Lie derivatives. We interpret these transformations as 'generalized coordinate transformations' in the doubled space by proposing(More)
We present a unified description of the low-energy limits of type-II string theories. This is achieved by a formulation that doubles the space-time coordinates in order to realize the T-duality group O(10,10) geometrically. The Ramond-Ramond fields are described by a spinor of O(10,10), which couples to the gravitational fields via the Spin(10,10)(More)

Abstract: We develop doubled-coordinate field theory to determine the α ′ corrections to the massless sector of oriented bosonic closed string theory. Our key tool is a string current algebra of free left-handed bosons that makes O(D,D)(More)
