| dc.description | Self-consistent system of spinor, scalar and BI gravitational fields is considered. Exact solutions to the field equations in terms of volume scale of the BI metric are obtained. Einstein field equations in account of the cosmological constant $Λ$ and perfect fluid are studied. Oscillatory mode of expansion of the universe is obtained. It is shown that for the interaction term being a power function of the invariants of bilinear spinor forms and $Λ> 0$ and given other parameters, e.g., coupling constant, spinor mass etc., there exists a finite range of integration constant which generates oscillatory mode of evolution. | |
