Scientific paper

The effect of particle creation in homogeneous anisotropic models is considered. The back reaction of the created particles on the metric is taken into account. As a result, the expansion of the universe becomes quasi-isotropic (with small vortex perturbations) starting from the Planck time. After some intermediate damping stage, the cosmological expansion approaches the Friedmann isotropic model. Observational consequences are discussed.
