Description
The ten-dimensional supergravity theory is a geometric low-energy effective theory and the equations of motion for its fields can be obtained from string theory by computing $\beta$ functions. With $d$ compact dimensions, an $O(d, d;\mathbb{Z})$ geometric structure can be added to it giving the supergravity theory with T-duality manifest. We use a particular projection to implement the so-called weak constraint and provide the generic solution in the one doubled space. This provides the double field theory in the one doubled space.
