Abstract: (Elsevier)
Superstring inspired models with an intermediate stage of symmetry breaking have severe cosmological problems associated with the breaking of discrete symmetries (domain wall problem) and with the need for a light decoupled scalar field (Polonyi problem). We show that an early period of inflation which gives the desired flatness, dilution of unwanted species, and density fluctuations also eliminates the problem associated with intermediate scale breaking. Mechanisms regenerating the baryon-number asymmetry are briefly described.
