Noncommutative Spacetime, Stringy Spacetime Uncertainty Principle, and Density Fluctuations
We propose a variation of spacetime noncommutative field theory to realize the stringy spacetime uncertainty relation without breaking any of the global symmetries of the homogeneous isotropic universe. We study the spectrum of metric perturbations in this model for a wide class of accelerating back...
