Expanding & Shearing Biachi Type-I Non-Static Cosmological Model in General Relativity

Abstract

We have investigated expanding, shearing and non- static Bianchi type-I cosmological models in General Relativity. To get deterministic model, we have assumed that shear (σ) is proportional to the expansion (θ) in the model which leads to A= (BC)ⁿ where A, B, C are metric potential and n is constant. Using the condition, we found a stiff fluid model. The various physical and geometrical aspects of model are also discussed.
