| Abstract: | Isothermal (isoinflaton) perturbations generated in cosmological models at the inflationary stage are discussed. The spectrum of such perturbations has been calculated for the example of a cosmological model with axion-type matter. The possibility of the cut-off of the spectrum at long wavelengths has been shown. This leads to the suppression of large-scale fluctuations of the temperature of the background radiation. |
