Description

We discuss Bianchi type-VII0 cosmology with a Dirac field in the Einstein—Cartan (E-C) theory and obtain the equations of the Dirac and gravitational fields in the E-C theory. A Bianchi type-VII0 inflationary solution is found. When (3)/16S2 - σ2 > 0, the Universe may avoid singularity. (geophysics, astronomy, and astrophysics)
