I shall present an overview of T-duality symmetric formalisms in which the dimension of target space is doubled and the sigma model supplemented with constraints. In particular I shall describe the equations that the background fields must satisfy. These are calculated by demanding the vanishing of the beta-functionals of the sigma model couplings in the doubled target space. I will demonstrate that the Weyl divergences for the duality symmetric string are equivalent to those of the standard sigma model and that the full beta-functionals are naturally interpreted as the field equations for a dimensionally reduced and O(d,d) invariant space time action.
