No manifest 𝑇 duality at order 𝛼′3
Original language description
When reduced from 10 to 10 -d dimensions tree-level string theory exhibits an O(d,d) symmetry. This symmetry, which is closely related to T duality, appears only after certain field redefinitions. We find a simple form for a subset of these redefinitions at order α′3 and show that they cannot be lifted to ten dimensions. This is inconsistent with "manifestly T duality invariant" approaches such as generalized geometry (in the uncompactified setting). Such formulations therefore seem not to be the correct language to describe string theory.
