Anisotropic Universe Models in Brans-Dicke Theory    [PDF]

M. Sharif, Saira Waheed

This paper is devoted to study Bianchi type I cosmological model in
Brans-Dicke theory with self-interacting potential by using perfect,
anisotropic and magnetized anisotropic fluids. We assume that the expansion
scalar is proportional to the shear scalar and also take power law ansatz for
scalar field. The physical behavior of the resulting models are discussed
through different parameters. We conclude that in contrary to the universe
model, the anisotropic fluid approaches to isotropy at later times in all cases
which is consistent with observational data.
