Unimodular SL(n,R) Gravity and E8 Physics

Authors: Frank Dodd Tony Smith Jr

Unimodular SL(n,R) Gravity in n-dimensional SpaceTime is related to E8 Physics in two ways: to 8-dim SpaceTime and to 4-dim Physical Minkowski M4 SpaceTime. The Unimodular SL(8,R) represents 8-dim SpaceTime as a generalized checkerboard of SpaceTime HyperVolume Elements. The Unimodular SL(4,R) has conformal structure effectively equivalent to that of MacDowell-Mansouri SU(2,2) Conformal Gravity and, further, is useful in resolving the strong CP problem.
