Bounce Behaviour of Kantowski-Sach Cosmological Model in General Relativity
Kantowski-Sach cosmological model has obtained in the general theory of relativity. The source for energymomentum tensor is assumed a perfect fluid. The field equations have solved by using special form of the average scale factor ( ) Ξ² Ξ² β ο£· ο£·ο£Έ ο£Ά  ο£¬ο£ ο£« β = β + 1 1 2 0 0 1 R(t) t t t proposed by Cai et al. The physical properties and the bouncing behavior of the model are also discussed.
Kaluza-Klein Barotropic Cosmological Models with Varying Gravitational Constant G in Creation Field Theory of Gravitation
Kaluza Klein cosmological models with varying G in Hoyle Narlikar creation field theory of gravitation for barotropic fluid distribution have been investigated. The solution of the field equations have been obtained by assuming that G=Al, where A is a scale factor and l is a constant. The physical properties of the model are studied.
Some Dust Cosmological Models with Time Dependent I(t) in Creation Field Cosmology
We have studied the Hoyle-NarlikarΓ’β¬β’s Creation-field cosmology for LRS Bianchi type-II, LRS Bianchi type-VI0, Plane Symmetric and Kantowski-Sachs universes with time dependent cosmological constant ΓβΊ(t) , when the universe is filled with dust distribution. To get deterministic model of the universe, a relation between shear (ΓΖ ) and expansion (ΓΒΈ ) is assumed. The physical aspects of the models are also discussed.
