DESCRIPTION: The Thouless-Anderson-Palmer (TAP) approach to the Sherringto
 n-Kirckpatrick mean field spin glass model was described in one of the ear
 liest papers on this model\, but has subsequently been a complementary rat
 her than the central component in the theory that has emerged in theoretic
 al physics and mathematics. In this this talk I will recall the TAP approa
 ch\, and describe how it can be reinterpreted as a variational principle i
 n the spirit of the Gibbs variational principle. Furthermore I will presen
 t a rigorous proof of this TAP-Plefka variational principle in the case of
  the spherical Sherrington-Kirkpatrick model\, which allows to compute the
  free energy based purely on a TAP analysis.\n
