Dualities from higher-spin supergravity

Higher spin N = 8 supergravity

The product of two N = 8 supersingletons yields an infinite tower of massless states of higher spin in four dimensional anti de Sitter space. All the states with spin s ≥ 1 correspond to generators of Vasiliev’s super higher spin algebra shsE(8|4) which contains the D = 4, N = 8 anti de Sitter superalgebra OSp(8|4). Gauging the higher spin algebra and introducing a matter multiplet in a quasi-a...

No - scale supergravity from higher dimensions 1

We discuss recent results on the interpretation of flux compactifications on certain Type IIB orientifolds in terms of gauged N –extended supergravities of no–scale type

DUALITIES IN THE CLASSICAL SUPERGRAVITY LIMITS Dualisations, dualities and a détour via 4k+2 dimensions

Duality symmetries of supergravity theories are powerful tools to restrict the number of possible actions, to link different dimensions and number of supersymmetries and might help to control quantisation. (HodgeDirac-)Dualisation of gauge potentials exchanges Noether and topological charges, equations of motion and Bianchi identities, internal rigid symmetries and gauge symmetries, local trans...
