DESCRIPTION:Abstract:\nReconstructing the interior structure of the Earth 
 from only the spectrum of its free oscillations is impossible for several 
 reasons. This kind of "spectral uniqueness" is beyond reach\, but a weaker
  result known as "spectral rigidity" is not. We discuss what it means if a
  model of the Earth is spectrally rigid and we give the first spectral rig
 idity result for a simple radial model. This is joint work with Maarten de
  Hoop and Vitaly Katsnelson
