Generalised Geometry and consistent truncation

Abstract: Consistent truncations of ten- and eleven- dimensions supergravity are useful tools in order to derive lower-dimensional effective theory, but are usually difficult to obtain. Generalised geometry provides a well suited framework to derive consistent truncations in arbitrary dimension and with different amount of supersymmetry, based on the notion of generalised G-structure. In this talk I will present first the general ideas in generic dimension and amount of supersymmetry. Then I will show how to apply the formalism to truncations to half-maximal supergravity in five dimensions. As concrete examples, I will present an M-theory truncation that contains the Maldacena Nunez solutions for M5-branes wrapped on a Riemann surface.
