Abstract
In an inflationary cosmology the phase transitions associated with intermediate mass scales may experience a large though not huge number of e-foldings before being finally completed. Extended structures (monopoles, strings, etc.) arising from such transitions are not necessarily inflated away. In an S0(10) model, for example, magnetic monopoles with mass ~ 1013 – 1014 GeV can occur at a level which is experimentally detectable. The topologically unstable string - wall system of axion models provides an important source of density fluctuations as a consequence of inflation.
