| Abstract: |
We review the embedding tensor technique which has been developed to study general embeddings of gauge groups in theories with a given rigid symmetry group. For extended supergravities this techniques classifies all possible supersymmetric deformations of the theory, so that it captures all possible flux compactifications in a group-theoretical setting. The first part of the lecture deals with the following topics: hidden symmetries, gauging and gauge group embeddings, the hierarchy of p-form gauge fields. The second part discusses the p-form hierarchy in 4 space-time dimensions, maximal supergravities and M-Theory degrees of freedom, and the ''end of the hierarchy''. |
