Peter Schupp: Geometry with fluxes
This short course provides an introduction to Generalized Geometry, which is a generalization of Riemannian geometry that naturally incorporates fluxes and symmetries of theories of extended objects (strings) and is a natural setting for the formulation of various gravity theories.
For supplemental background material on string compactifications, please see the very nice set of lectures by Mariana Grana and Hagen Triendl . The intriguing relation of graded (super Poisson) geometry and generalized geometry is investigated in . In  we review the emergence of non-associative structures in the presence of non-geometric background fluxes.
