Abstract

Exact solutions to the self-consistent system of equations of interacting spinor and scalar fields are considered within the scope of Bianchi type VI cosmological model filled with a perfect fluid in account of a $\Lambda$-term have been obtained. The role of the spatial inhomogeneity has been studied. It has been shown that the introduction of a positive $\Lambda$, the most widespread kind of dark energy, leads to the rapid growth of the universe, while the negative one, corresponding to an additional gravitational energy gives rise to an oscillatory or non-periodic mode of expansion.
