Anisotropic cosmological model created by quantum polarization of vacuum

The authors have found a homogeneous anisotropic nonsingular metric of space-time with a six-parametric symmetry group, which metric is created by vacuum polarization of the quantum fields of matter by a self-consistent gravitational field in the absence of classical matter. They calculated the mean value of the energy-momentum tensor of massless conformally covariant fields and a nonzero-mass scalar field in this metric. Green's function of this scalar field is calculated, too
