ANISOTROPIC COSMOLOGICAL MODELS OF BIANCHI TYPE I, V, IX IN GRAVITY THEORY WITH NON-MINIMAL COUPLING

Galeev R.G., Sushkov S.V.

In this work we analyze behaviour of anisotropy in cosmological models of Bianchi type I, V, IX in gravity theory with non-minimal kinetic coupling. Deriving background equations from non-minimally coupled action, we obtain generalized system of equations. Further, we numerically analyze the solutions of this system, considering the anisotropy on early and late stage of universe evolution.
