BIANCHI TYPE III INFLATIONARY UNIVERSE WITH FLAT POTENTIAL AND CONSTANT DECELERATION PARAMETER IN GENERAL RELATIVITY

Bianchi Type III inflationary model with flat potential and massless scalar field is investigated. To get an inflationary universe, we have considered a flat region in which the potential V(phi) is constant and decelerating parameter is also constant. We find that the spatial volume increases with time representing inflationary scenario. The Hubble parameter decreases with time. The Higgs field evolves slowly but the universe expands. The models represent decelerating and accelerating phases of universe and isotropize at late time. These results match with recent astronomical observations. The models also have Point Type singularities.
