Description
The 11-dimensional supergravity is famously the unique maximal supergravity in the maximal possible number of spacetime dimensions. I will discuss the construction of a novel non-relativistic supergravity in 11-d, by taking a limit of the 11-dimensional supergravity. This limit breaks the local Lorentz symmetry from SO(1,10) to SO(1,2) x SO(8) and so is linked to the appearance of membranes in 11 dimensions. As well as providing access to a non-relativistic corner of quantum gravity, this limit is U-dual to the Matrix Theory description of M-theory. Based on work in progress with E. Bergshoeff, J. Lahnsteiner and J. Rosseel.
