Tilted Kantowski–Sachs cosmological model in Brans–Dicke theory of gravitation
Preview AbstractTilted Kantowski–Sachs cosmological model in Brans–Dicke theory for perfect fluid has been investigated. The general solution of field equations in Brans–Dicke theory for the combined scalar and tensor field are obtained by using power law relation. Also, some physical and geometrical parameters are obtained and discussed.
Tilted cosmological model consisting two forms of dark energy
Preview AbstractWe have presented the tilted cosmological model consisting of two forms of dark energy. The behavior of different stages of the Universe in tilted models is studied with the help of dark energy contained in our Universe to be part of quintessence which is a homogeneous minimally coupled scalar. To get the deterministic model, we have assumed a power law of gravitational constant G. We also investigated the behavior of some physical and geometrical parameters.
