Kantowski -Sachs Inflationary Cosmological Model with Bulk Viscosity and Varying Cosmological Constant in General Relativity
Journal Title: UNKNOWN - Year 2015, Vol 4, Issue 3
Abstract
Abstract:- Kantowski-Sachs inflationary cosmological model with bulk viscosity is investigated. To get the deterministic model of the universe, we assume the relation between metric potentials R=S^n where R and S are metric potentials and n is a constant. It is found that the cosmological constant is positive and is a decreasing function of time, which is supported by results from recent supernova observations. To get an inflationary universe, we have considered flat region in which the potential V is constant. Some physical and geometrical properties of the models are also discussed.
