SUMMARY:Sébastien FERENCZI (I2M\, CNRS\, Marseille): Languages of (more an
 d more) general interval exchanges
DESCRIPTION:Sébastien FERENCZI: The languages generated by interval exchan
 ge transformations have been characterized by the authors (2008) and Belov
 -Cernyatev (2010) under some extra conditions on the system. Lifting these
  conditions leads us to consider successively natural codings of standard 
 interval exchanges\, natural codings of affine interval exchanges\, groupe
 d codings of affine interval exchanges\, and natural codings of generalize
 d interval exchanges. We show that these four classes of languages are str
 ictly increasing\, and give necessary and\\or sufficient (but not all equa
 lly explicit) combinatorial criteria to describe each of them. These work 
 also\, mutatis mutandis\, for interval exchanges with flips.\nExceptionnel
 lement au CMI.\n\n&nbsp\;
