M-theory origin of N=8 gauged supergravities

Conferencia; String Phenomenology 2015; 2015

Supergravity theories are generally believed to describe some low-energy approximation of string theory models. There is, however, a huge landscape of 4-dimensional supergravity models whose higher-dimensional origin is not clear yet. This is already true for the most constrained scenario of maximal supergravities. In this talk we will review the current understanding of this problem with special emphasis in the uplifting of non compact supergravites and their relation with Exceptional Generalised Geometry.
