E8 duality and dual gravity    [PDF]

Hadi Godazgar, Mahdi Godazgar, Malcolm J. Perry

We construct the non-linear realisation of the E8 motion group and compare this with the bosonic sector of eleven dimensional supergravity. The construction naturally leads to the introduction of a new potential field. We identify this new field with the dual gravity field by considering the reduction of the eleven-dimensional theory to three dimensions.
