Summary:The dynamic role of primordial black holes in the early Universe is examined in terms of their formation and properties of the mass distribution. Particular attention is given to the early density perturbations caused by the presence of black holes. The disturbances in matter distribution are suggested to have led to the formation of galaxies and galactic clusters. An epoch is defined in which the turbulent energy density and the gaseous component of primordial black holes could predominate over effects of the background matter. A non-Friedmann expansion of the Universe would then be possible. The mass spectrum is described in terms of deviations of a random field expressed as the averaged value of the random field of perturbations in a volume of specified radius. Three possible variations are suggested for the Carr-Hawking criteria for black hole formation.
