Einstein Static Universe in Rastall Theory of Gravity

28 Oct 2017 Darabi F. Atazadeh K. Heydarzade Y.

We investigate stability of the Einstein static solution against homogeneous scalar, vector and tensor perturbations in the context of Rastall theory of gravity. We show that this solution in the presence of perfect fluid and vacuum energy originating from conformally-invariant fields is stable... (read more)
