Generalised geometry provides a well suited frame work to derive consistent truncations in arbitrary dimension and with diff erent amount of supersymmetry\, based on the notion of generalised G-struc ture. In this talk I will present first the general ideas in generic dimen sion and amount of supersymmetry. Then I will show how to apply the formal ism to truncations to half-maximal supergravity in five dimensions. As con crete examples\, I will present an M-theory truncation that contains the M aldacena Nunez solutions for M5-branes wrapped on a Riemann surface.\n LOCATION:https://researchseminars.org/talk/EGSS/5/ END:VEVENT END:VCALENDAR
