To discuss the following Bianchi cosmological models – Type–I cosmological model with respect to scalar tensor theory of gravitation. Type–II string cosmological model in Saez–Ballester theory of gravitation. Type–V cosmological model with perfect fluid and heat flow in Saez – Ballester theory of gravitation with deceleration parameter. 2. To evolve a model for accelerating bulk viscous Friedman Robertson Walker universe with respect to scale covariant theory of gravitation.enThesis
