摘要：

We have studied anisotropic and homogeneous Locally Rotationally Symmetric (LRS) Bianchi type-I, Bianchi type-V, Bianchi type-III, Bianchi type-VI0, and Kantowaski-Sachs space-times with variable equation of state (EoS) parameter (w) in General Relativity. A special form of deceleration parameter (q) which gives an early deceleration and late time accelerating cosmological model has been utilized to solve the field equations. The geometrical and physical aspects of the models are also studied.
