DESCRIPTION:Co-authors: Cyril Houdayer (Universit&eacute\; Paris Sud) and 
 Dimitri Shlyakhtenko (UCLA).<br>Free Araki-Woods factors are a free probab
 ility analog of the type III hyperfinite factors. They were introduced by 
 Shlyakhtenko in 1996\, who completely classified the free Araki-Woods fact
 ors associated with almost periodic orthogonal representations of the real
  numbers. I present a joint work with Houdayer and Shlyakhtenko in which w
 e completely classify a large class of non almost periodic free Araki-Wood
 s factors. The key technical result is a deformation/rigidity criterion fo
 r the unitary conjugacy of two faithful normal states on a von Neumann alg
 ebra.<br><br>
