We present the details of the recently constructed E 6 (6)-covariant extension of 11-
dimensional supergravity. This theory requires a 5+ 27-dimensional spacetime in which the …

The low-energy effective theories describing string compactifications in the presence of
fluxes are the so-called gauged supergravities: deformations of the standard Abelian …

Deformations of maximal supergravity theories induced by gauging non-abelian subgroups
of the duality group reveal the presence of charged M-theory degrees of freedom that are not …

All maximal supergravities in four space-time dimensions are presented. The ungauged
Lagrangians can be encoded in an E 7 (7)\Sp (56; Bbb R)/GL (28) matrix associated with the …

A bstract We develop in detail the general framework of consistent Kaluza-Klein truncations
from D= 11 and type II supergravities to gauged maximal supergravities in two dimensions …

A bstract We construct the first complete exceptional field theory that is based on an infinite-
dimensional symmetry group. E 9 exceptional field theory provides a unified description of …

We construct generalized diffeomorphisms for E 9 exceptional field theory. The
transformations, which like in the E 8 case contain constrained local transformations, close …

We present a systematic account of supergravity theories in which the global scaling
symmetry is gauged. This generalizes the standard gaugings of non-abelian off-shell …

A bstract Eleven-dimensional supergravity on S 8× S 1 is conjectured to be dual to the M-
theory matrix model. We prove that the dynamics of a subset of fluctuations around this …

A bstract We construct the scalar potential for the exceptional field theory based on the affine
symmetry group E 9. The fields appearing in this potential live formally on an infinite …
