Observing the de Sitter Space Propagator

Abstract
The primordial fluctuations in the mass density may have arisen from quantum fluctuations in a scalar field that occurred during an inflationary era. Fluctuations which arose in this way can be highly non-Gaussian. Also the bad infrared properties of the propagator for a massless scalar field in de Sitter space can translate itself into a power spectrum, for the two-point spatial correlation of objects that do not trace the mass, which behaves like K^(-3), at small wavenumbers k.
