Sažetak
Kantowski-Sachs cosmological models with perfect fluid and time varying G and Λ are presented. Exact solutions of the field equations are obtained by using the scalar of expansion proportional to the shear scalar θ ∝ σ, which leads to a relation between the metric potentials A = Bn, where n is a constant. The corresponding physical interpretation of the cosmological solutions are also discussed.
