We will discuss supersymmetric reductions of type II and M-theory down to four dimensions, in the language of exceptional generalized geometry (EGG).
EGG is the extension of generalized complex geometry which also geometrizes the RR fields, and is therefore the relevant language to use in M-theory.
After a brief introduction to EGG, we will present the algebraic structures that encode all information about the lower-dimensional action, concentrating on the case of N=2 supersymmetry. We will show, in particular, that these structures have a nice description using an 8-dimensional tangent space, where they look like pure spinors as in generalized complex geometry.
