Lorentz-invariant membranes and finite matrix approximations
Published 23 Jan 2011 in hep-th | (1101.4403v1)
Abstract: The question of Lorentz invariance for finite N approximations of relativistic membranes is addressed. We find that one of the classical manifestations of Lorentz-invariance is not possible for NxN matrices (at least when N=2 or 3). How the symmetry is restored in the large N limit is studied numerically.
