Local beta-shifts and alpha'-corrections

Abstract: Local (i.e. non-constant) beta shifts of O(D,D) are a solution-generating technique in supergravity, when additional conditions are imposed on beta. In the literature this construction has been known as "homogeneous Yang-Baxter deformation", and it was first introduced to generate integrable deformations of 2d sigma-models. Interest on such deformations is also motivated by their relation to non-abelian T-duality. In this talk I will review some aspects of this subject and I will explain how to obtain alpha'-corrections for the deformed backgrounds by exploiting the Double Field Theory formulation.
