Differential geometry of Lie algebroids for non-geometric string theory

Abstract: In this talk, first the appearance of non-geometric fluxes in string theory is reviewed. Then, to describe these fluxes, the framework of Lie algebroids is introduced and illustrated by two examples. Furthermore, a differential geometry calculus is developed, and an action for non-geometric fluxes is constructed. Finally, the connection to string theory will be established, and - depending on time - equations of motion and solutions thereof will be discussed.
