TL;DR: In this article, the action and transformation laws of supergravity in 11 dimensions were presented, which is expected to be closely related to the O(8) theory in 4 dimensions after dimensional reduction.

TL;DR: In this paper, the SO(8) supergravity theory was derived by dimensional reduction of the super gravity theory in 11 dimensions to 4 dimensions, where the equations of motion are invariant under the global non-compact group E7(+7).

TL;DR: The Lagrangian and transformation laws of the coupled Yang-Mills-matter-supergravity system for unextended n = 1 local supersymmetry were derived in this article.

TL;DR: In this paper, the choice of a particular class of Einstein spaces for the Kahler manifold of the hidden sector leads to a vanishing cosmological constant without unnatural fine tuning, and the resulting low energy softly broken globl supersymmetry for the matter fields is the same as in the case of factorized superpotential models with a flat Kahler metric.

TL;DR: In this article, the SO(8) supergravity action is constructed in closed form and a local SU(8)-group as well as the exceptional group E7 are invariances of the equations of motion and of a new first order lagrangian.
