Abstract:
This talk gives the basics of extended geometry, with a focus on the gauge trans- formations, the generalised diffeomorphisms. Some global issues are discussed. I also go into some detail about how the formalism can be made to allow for a geometric derivation of discrete duality transformations and of monodromies for non-geometric field configurations.
