Some LRS Bianchi Type-II String-Dust Cosmological Models in General Relativity

摘要

Some LRS Bianchi type-II string- dust cosmological models are investigated in whichthe expansion (θ) is assumed to be proportional to the shear (σ). To obtain exact solutions,the Einstein’s field equations have been solved for two cases (i) Reddy string and (ii) Nambustring. The physical and geometrical behaviour of these models are discussed.
