Description
We investigate the tachyon-dilaton-metric system to study the open-quotes graceful exitclose quotes problem in string theoretic inflation, where the tachyon plays the role of the scalar field. From the phase-space analysis, we find that the inflationary phase does not smoothly connect to a Friedmann-Robertson-Walker expanding universe, thereby providing a simple tachyonic extension of the recently proved stringy no-go theorem. copyright 1997 The American Physical Society
