Abstract:

Exact solutions to the Einstein Dirac Klein-Gordon equations are found in Bianchi type-I and type-V spacetimes. When the spinor field is massive, the Bianchi type-I universe has singularities of the Zel dovich type, and it may begin anisotropically at a singularity, leading to a dust-filled Friedmann stage at late times. For ghost neutrinos we get an axisymmetric Zel dovich universe. These solutions have particle horizons. For the Bianchi type-V model there exist solutions which begin at a singularity, tending to flat spacetime at late times. In this case the neutrinos are not ghost ones. © 1990 The American Physical Society.
