A much studie d class of truncations are generalised Scherk–Schwarz (gSS) reductions. While the principle of such truncations is well-understood and many exampl es are known\, there is no complete classification of gSS reductions. Conv ersely\, it can be difficult to know if a specific gauged supergravity can arise from a generalised Scherk–Schwarz truncation of some higher-dimen sional model.\nI will review some results on the general recipe for constr ucting generalised Scherk–Schwarz uplifts of gauged supergravities and o n the conditions for such uplifts to exist. I will then discuss work in pr ogress in rephrasing such uplift conditions as linear constraints and comm ent on the extension to three-dimensional gauged supergravities and lower\ , where the associated exceptional geometries become more complicated.\n LOCATION:https://researchseminars.org/talk/EGSS/9/ END:VEVENT END:VCALENDAR
