Gauged Supergravities , Tensor Hierarchies , and M - Theory
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 necessarily contained in supergravity. The relation with Mtheory degrees of freedom is confirmed by the representation assignments under the duality group of the gauge charges and the ensuing vector and tensor gauge f...
متن کاملVacua of Maximal Gauged D = 3 Supergravities
We analyze the scalar potentials of maximal gauged three-dimensional supergravities which reveal a surprisingly rich structure. In contrast to maximal supergravities in dimensions D ≥ 4, all these theories admit a maximally supersymmetric (N = 16) ground state with negative cosmological constant Λ < 0, except for the gauge group SO(4, 4)2, for which Λ = 0. We compute the mass spectra of bosonic...

We describe generalizations of the manifestly E6(6) covariant formulation of five-dimensional gauged maximal supergravity with regard to the structure of the vector and tensor fields. We indicate how the group-theoretical structures that we discover seem to play a role in gauged supergravities in various space-time dimensions.
متن کاملCompact and Noncompact Gauged Maximal Supergravities in Three Dimensions
We present the maximally supersymmetric three-dimensional gauged supergravities. Owing to the special properties of three dimensions — especially the on-shell duality between vector and scalar fields, and the purely topological character of (super)gravity — they exhibit an even richer structure than the gauged supergravities in higher dimensions. The allowed gauge groups are subgroups of the gl...
متن کاملGauged N=4 Supergravities
We present the complete gauged N = 4 (half-maximal) supergravities in four and five spacetime dimensions coupled to an arbitrary number of vector mul-tiplets. The gaugings are parameterized by a set of appropriately constrained constant tensors, which transform covariantly under the global symmetry groups SL(2) × SO(6, n) and SO(1, 1) × SO(5, n), respectively. In terms of these tensors the univ...
