Description
In this talk we will discuss some geometric aspects of double field theory. We will argue that the geometric structure of DFT lies in between two pre-Courant algebroids, related to one of them by a projection map and to the other by solving the strong constraint. The structure is not itself a (pre-)Courant algebroid. The proposed picture provides a geometric origin for DFT and its strong constraint, and at the same time it allows for a precise geometric definition of a DFT algebroid.
