Duality invariance and higher derivatives

Abstract: T-duality implies that string theories, once compactified on a d-dimensional torus, must have a global O(d,d)symmetry. The exact interplay between this duality and α'-corrections is however not known. In this talk, I will expose new tools to tackle this problem and show, considering the bosonic string theory to first order in α', that this symmetry requires a Green-Schwarz type mechanism for α'-deformed O(d,d) transformations.
