  Evolution of an anisotropic universe described by a Bianchi type I (BI) model
in presence of nonlinear spinor field has been studied by us recently in a
series of papers. On offer the Bianchi models, those are both inhomogeneous and
anisotropic. Within the scope of Bianchi type VI (BVI) model the
self-consistent system of nonlinear spinor and gravitational fields are
considered. The role of inhomogeneity in the evolution of spinor and
gravitational field is studied.
