Doubled, exceptional and new generalised geometries

Supergravity theories are naturally described in terms of certain generalised geometries, which combine diffeomorphisms with the other gauge symmetries of the model. Moreover, certain string backgrounds that defy a supergravity description can be captured by extensions of generalised geometry. I will describe the basics of these frameworks and recent results on the description of massive IIA supergravity, plus some work(s) in progress.

Unusual hour.
