Mathematics and Applications of Branes in String and M-theory

I will show how the equations of motion of double field theory can also be derived as the one-loop background field equations of a double sigma model, both being the vanishing of the generalised Ricci tensor. This raises the possibility of deriving higher order corrections to double field theory from a sigma model approach.
