摘要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 3S2/16−σ2 > 0, the Universe may avoid singularity.
Abstract：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 3S2/16−σ2 > 0, the Universe may avoid singularity.
