ANISOTROPIC AND INHOMOGENEOUS COSMOLOGICAL MODELS IN THE SCALAR-TENSOR THEORY OF GRAVITY WITH NON-MINIMAL KINETIC COUPLING

Gatin K.A., Muharlyamov R.K., Sushkov S.V.

In this paper, we consider a gravitating scalar field with a non-minimal kinetic coupling to the curvature. The field equations are written in the polarized Gaud? metric. The corresponding space-time is anisotropic and inhomogeneous. In our research, we want to obtain mechanisms for the transition of the Universe from an inhomogeneous phase to a homogeneous one in the framework of Horndesky’s theory. In this paper, we restrict ourselves to a preliminary analysis of the field equations.

Keywords: gravitational waves, algebraic classification of Petrov, Weyl matrices, a superposition (composition) principle of space types, linearised Einstein equations.
