Idea

supergravity in dimension 4.

The maximally supersymmetric N=8N = 8-version arises from type II supergravity in 10 dimension by compactification on a 6-torus.

The N=1N=1-version arises from KK-reduction via M-theory on G2-manifolds. This hosts the super 2-brane in 4d.

On N=1N=1 d=4d = 4 supergravity

There are two different off-shell formulations, the “old minimal”

and the “new minimal” supergravity

These two versions were later understood to be two different gauge fixings of N=1 d=4 coformal supergravity. Yet other gauge fixings are discussed in
