Abstract
Low energy effective string cosmology in higher dimensions with a specific type of quantum-like potential is investigated and some features are explored in some details. It was shown that in four and five dimensions, the universe may exist from inflation gracefully with no reheating, deflates in the radiation dominated epoch and finally expands acceleratedly in the dust epoch while the scalar field decays in time.
Keywords
low energy effective string actions; quantum-like potential; deflation; accelerated expansion
