In this talk\, I will present a general framework for uplifti ng non-maximal gauged supergravities using exceptional field theory and ge neralised geometry\, extending techniques previously available only for ma ximal supergravities. Our method put constraints on the internal manifolds \, which must admit an effective action of the gauge group\, and we show t hat the consistency of the uplift reduces to a PDE on the quotient of the internal manifold by this action. I will illustrate the framework through the complete classification of type IIB uplifts of four-dimensional half-m aximal SO(4)-gauged supergravity. This will provide consistent truncations around any of the D’Hoker–Estes–Gutperle AdS_4 solutions.\n LOCATION:https://researchseminars.org/talk/AnLy/61/ END:VEVENT END:VCALENDAR
