Anisotropic cosmological models of Bianchi type I, V, IX in Horndeski gravity theory

In this work we analyze behavior of anisotropy in cosmological models of Bianchi type I, V, IX in Horndeski gravity theory. Deriving background equations from Horndeski action, we obtain generalized system. Further, we numerically analyze solutions of diverse scalar-tensor gravity theories within Horndeski theory framework, considering the anisotropy on early and late stage of universe evolution.
