In this paper we investigate to which extent noncommutativity, a intrinsically quantum property,may influence the Friedmann-Robertson-Walker cosmological dynamics at late times/large scales.
This paper discusses the observed flat rotation curves of galaxies in the context of noncommutative geometry. The energy density of such a geometry is diffused throughout a region due to the uncertain...

Using the Seiberg-Witten map, we obtain a quantum electrodynamics on a
noncommutative space, which has arbitrary charge and keep the gauge
invariance to at the leading order in theta. The one-loop d...
