Kantowski-Sachs Dark Energy Cosmological Model in General Scalar Tensor Theory of Gravitation

Abstract

Spatially homogeneous Kantowski - Sachs dark energy cosmological models in Nordtvedt (1970) general scalar tensor theory of gravitation with the help of a special case proposed by Schwinger (1970) are obtained. These anisotropic as well as isotropic exact models are free from singularities.Some important features of the models, thus obtained, have been discussed. These exact models represent not only the early stages of evolution but also the present universe.
