Findings

Inhomogeneity affects the evolution of spinor and gravitational fields.

Nonlinear spinor fields can influence anisotropic universe dynamics.

Extension of previous Bianchi I studies to Bianchi VI models.

Abstract

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.
