Scientific paper

Calculations are performed which show that allowance for the role of 'free particles' (gravitons) in the Friedmann world model leads to novel types of pregalactic perturbations, called zero vortices. Metric perturbations are obtained for these zero vortices. A comparison with the hydrodynamic case indicates that these perturbations are quite small and, therefore, will not affect helium formation at the early stage of expansion of the 'hot' Universe.
