Martin Cederwall, Chalmers University of Technology: Extended (double or exceptional) geometry is a framework where diffeomorphisms and certain tensor gauge transformations are united in order to reproduce duality symmetries in string theory ~ M-theory. I will review the basics of the formalism, focussing on local symmetries and geometric concepts, and make the connection to duality symmetries precise. If time allows, generalisation to supergeometry will be discussed, as well as situations where “dual gravity” becomes relevant.
