Résumé :

In this paper, we provide an algorithm to perform the uplift of non-maximal Gg-gauged supergravities to type IIB or 11D supergravities. Using tools of exceptional field theory and generalised geometry, we show that the internal manifold admits a Gg-action, and that consistency of the uplift is equivalent to solving a simpler PDE on the quotient Mint/Gg. As an application, we classify all possible uplifts of pure half-maximal four-dimensional SO(4)-gauged supergravity to type IIB and we recover consistent truncations around any of the D’Hoker-Estes-Gutperle solutions [JHEP06 (2007) 022].
