DESCRIPTION:Duality symmetries\, such as the T- and U-dualities of string a
 nd M-theory\, can impose constraints typically associated with supersymmet
 ry — without introducing additional degrees of freedom. To set the stage
 \, I will give a brief introduction to generalised geometry\, and double a
 nd exceptional field theories — duality-covariant frameworks that geomet
 rise O(d\,d)- and E(d)-group\, of T- and U-duality.\n\nBuilding on this\, 
 I will explore the constraining power of these duality symmetries through 
 two examples. First\, I will present a novel derivation of the constraints
  that the T-duality group O(d\,d) places on the NS–NS supergravity actio
 n\, using deformation quantisation of differential graded manifolds. Secon
 d\, I will show how an E(d)-covariant phase space approach can be used to 
 derive a brane scan for the standard half-BPS branes of string and M-theor
 y\, and give a unified form to their dynamics.
