Idea

Reductions of 11-dimensional supergravity on a 4-dimensional space to a 7-dimensional theory.

Properties

U-duality

Maximal 7d supergravity has SL(5,)SL(5,\mathbb{Z})-U-duality (Kumar-Vafa 96, section 3.4, Rozali 97).

Holography

The AdS7/CFT6-correspondence relates 7-dimensional supergravity on asymptocially 7d anti de Sitter spacetimes to the 6d (2,0)-superconformal QFT.

There are also gaugings for non-compact groups

The N=2N=2 Sp(1)Sp(1)-gauged theory was described in

By reduction from 10d/11d supergravity

The following references discuss construction of full 7d sugra theories or of their solutions by KK-reduction from 11-dimensional supergravity or 10d type II supergravity.

The construction of 7d supergravity by reduction from 11-dimensional supergravity was first indicated in
