Kaluza-Klein Reduction of Low-Energy Effective Actions: Geometrical Approach (1704.01123v2)

Abstract: Equations of motion of low-energy string effective actions can be conveniently described in terms of generalized geometry and Levi-Civita connections on Courant algebroids. This approach is used to propose and prove a suitable version of the Kaluza-Klein-like reduction. Necessary geometrical tools are recalled.
