Bianchi Type V Inflationary Universe with Flat Potential & Constant Deceleration Parameter in General Relativity

Abstract

Bianchi Type V inflationary model with flat potential and massless scalar field is investigated. To get the deterministic model of the universe, we assume that deceleration parameter is constant. The model represents decelerating and accelerating phases of the universe. The model initially represents anisotropic phase of the universe but it isotropizes for large values of time. The Hubble parameter (H) is initially large but decreases with time. The Higgs field (f) evolves slowly but the universe expands due to vacuum field energy. The spatial volume increases with time representing inflationary scenario.
