Large Anisotropic Kantowski-Sachs Dark Energy Cosmological Models in General Relativity

Abstract

The anisotropic Kantowski-sach space-time containing perfect fluid is studied to explore dark energy cosmological models in general theory of relativity. Exact solutions of Einstein's field equations are obtained which correspond to a dark energy cosmological model with constant EoS parameter. An algorithm is derived to generate solutions of the field equations starting from known solution of the same type. Starting from the model I, an anisotropic Kantowski-sachs dark energy cosmological model II is generated with variable EoS parameter. The physical and geometrical aspects of the model II are discussed.
