On uplift conditions for gauged supergravities

Abstract: Supergravity theories can be consistently truncated to lower dimensional gauged supergravities, which has many applications especially for the purpose of solution generation. A much studied class of truncations are generalised Scherk–Schwarz (gSS) reductions. While the principle of such truncations is well-understood and many examples are known, there is no complete classification of gSS reductions. Conversely, it can be difficult to know if a specific gauged supergravity can arise from a generalised Scherk–Schwarz truncation of some higher-dimensional model. I will review some results on the general recipe for constructing generalised Scherk–Schwarz uplifts of gauged supergravities and on the conditions for such uplifts to exist. I will then discuss work in progress in rephrasing such uplift conditions as linear constraints and comment on the extension to three-dimensional gauged supergravities and lower, where the associated exceptional geometries become more complicated.
