Duality Invariant Actions and Generalised Geometry
David S. Berman, Hadi Godazgar, Malcolm J. Perry +1
We construct the non-linear realisation of the semi-direct product of E(11) and its first fundamental representation at lowest order and appropriate to spacetime dimensions four to…
The local symmetries of M-theory and their formulation in generalised geometry
David S. Berman, Hadi Godazgar, Mahdi Godazgar +1
In the doubled field theory approach to string theory, the T-duality group is promoted to a manifest symmetry at the expense of replacing ordinary Riemannian geometry with generali…
Boundary Terms in Generalized Geometry and doubled field theory
David S. Berman, Edvard T. Musaev, Malcolm J. Perry
We propose a boundary action to complement the recently developed duality manifest actions in string and M-theory using generalized geometry. This boundary action combines the Gibb…
SO(5,5) duality in M-theory and generalized geometry
David S. Berman, Hadi Godazgar, Malcolm J. Perry
We attempt to reformulate eleven dimensional supergravity in terms of an object that unifies the three-form and the metric and makes the M-theory duality group manifest. This short…
