nLab D=7 supergravity

Idea

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

Properties

U-duality

Maximal 7d supergravity has $SL(5,\mathbb{Z})$-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.

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 from 10d type II supergravity.

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

• Peter Freund, M. A. Rubin, Dynamics Of Dimensional Reduction, Phys. Lett. B 97 2 (1980) 233-235 [doi:10.1016/0370-2693(80)90590-0]

via what is now called Freund-Rubin compactification.

That their Ansatz is indeed consistent has been shown in

• Horatiu Nastase, Diana Vaman, Peter van Nieuwenhuizen, Consistent nonlinear KK reduction of 11d supergravity on $AdS_7\times S_4$ and self-duality in odd dimensions Phys.Lett. B469 (1999) 96-102 (arXiv:hep-th/9905075)
