Summary: We study N = 8 supergravity deformed by the presence of the candidate counterterms. We show that even though they are invariant under undeformed E 7(7) , all of the candidate counterterms… Expand

The N=8 supergravity theories in four (and five) dimensions with non-compact gauge groups are obtained from eleven- (and ten-) dimensional supergravities in backgrounds with non-compact internal… Expand

New gaugings of four-dimensional N = 8 supergravity are constructed, including one which has a Minkowski space vacuum that preserves N = 2 supersymmetry and in which the gauge group is broken to… Expand

The authors show that all known solutions of the N=2 non-chiral d=10 supergravity theory can, by a simple procedure, be obtained from the known Freund-Rubin type solutions of D=11 supergravity. This… Expand

IIB supergravity is reformulated with a manifest local USp(8) invariance that makes the embedding of five-dimensional maximal supergravities transparent. In this formulation the ten-dimensional… Expand
