MATTER CREATION AND PRIMORDIAL CMB SPECTRUM IN THE INFLATIONLESS MILNE-LIKE COSMOLOGIES
Abstract
The primordial spectrum of scalar particleʼs density perturbations is calculated. On the assumption of spectrum universality, i.e., a mean energy density and a typical value of inhomogeneity can be chosen arbitrarily, the form of the spectrum turns out to be completely defined. It is close to the flat Harrison – Zeldovich spectrum, but with the suppression of low-frequency modes.
