Idea

Theories of supergravity in dimension l<11l \lt 11 always contain a global symmetry called R-symmetry (a remnant of the full 11-dimensional supergravity Spin(10,1)Spin(10,1)-symmetry after KK-compactification). In some cases this is promoted to a local symmetry, such that there is a gauge field (connection on a bundle) with coefficients in that group. These are called gauged supergravity theories.

Properties

From dimensional reduction

In many cases, gauged supergravity theories are obtained by dimensional reduction from 11-dimensional supergravity or type II supergravity, which themselves do not contain a gauge field but higher degree fields (“fluxes”), the supergravity C-field and the B-field respectively. These induce gauged supergravities (e.g. Samtleben 08, figure 1). The gauge groups are the U-duality groups of the compactification (e.g. Samtleben 08, table 1).

From double and exceptional field theory

Exceptional field theory (but also double field theory) reduces to gauged supergravity under generalized Scherk-Schwarz reduction, i.e. a dimensional reduction combined with U-duality (or just T-duality) twists.
