Hypersurface-Homogeneous Cosmological Models with Anisotropic Dark Energy & Massive Scalar Field in Lyra Manifold

Abstract

In this paper, Einstein's field equations are considered for the hypersurface-homogeneous space-time with anisotropic dark energy and massive scalar field in Lyra manifold. Exact solutions of the field equations are obtained using the assumptions that (i) the shear scalar in the model is proportional to the scalar expansion and (ii) a relationship between the derivatives of the metric function and the scalar field, which represent expanding, shearing and non-rotating cosmological models of the universe. The physical and geometrical features of the models are discussed.
