E(11)-extended spacetime and gauged supergravities

Understand

We formulate all the five dimensional gauged maximal supergravity theories as non-linear realisations of the semi-direct product of E_{11} and a set of generators which transform according to the first fundamental representation l of E_{11}.

• The latter introduces a generalised space-time which plays a crucial role for these theories.
• We derive the E_{11} and l transformations of all the form fields and their dynamics.
• We also formulate the five dimensional gauged supergravity theories using the closure of the supersymmetry algebra.
